Spectrum analyzer, vector network analyzer and RF signal generator are also called RF components. Thanks to the commercialization of 5G, new infrastructure projects and the rapid advancement of intelligent networked vehicles in recent years, the market scale of RF components in China has grown rapidly, which is faster than the global market. At the same time, the three RF components continue to play the role of "small caliber and big drive", and through their own technological progress, they will drive the further development of downstream trillion-dollar markets such as 5G, semiconductors and Internet of Things.
At the same time, with the rapid development of China market, domestic substitution has become the general trend. For example, Jin Jiu and other domestic manufacturers have broken through technical barriers, devoted themselves to brand building and attached importance to market cultivation and construction, and embarked on a sustainable road of domestic substitution.
1, development status of China RF market.
-Overview of three RF components (spectrum analyzer, vector network analyzer and RF signal generator)
spectrum analyzer
According to the national standard GB/T11461-2013 "General Specification for Spectrum Analyzers", the spectrum analyzer is an instrument that can effectively display various spectrum components (sine waves) that make up time domain signals in frequency domain.
The spectrum analyzer can display the frequency domain characteristics of signals in analog or digital mode, and realize the measurement of signal distortion, modulation degree, stability and other parameters. In the field of RF, it has the reputation of "RF multimeter". The traditional spectrum analyzer is based on the principle of "sweeping frequency". The front-end circuit is a receiver with a certain bandwidth. The input signal is converted by the frequency converter and output by the filter. The filtered output is used as the vertical component and the frequency is used as the horizontal component. The coordinate picture is on the oscilloscope screen, which is the spectrum diagram of the input signal. With the rapid development of integrated circuit technology, fast A/D conversion technology, frequency synthesis technology, digital signal processing technology and microprocessor technology, the function and performance of spectrum analyzer have been greatly expanded and improved.
Modern high-end spectrum analyzer adopts fast Fourier transform technology. On the one hand, this technology decomposes the measured signal into independent frequency components to achieve the same results as the traditional spectrum analyzer, on the other hand, it digitizes the measured signal, so that the spectrum analyzer has the functions of vector signal analysis and real-time spectrum analysis. Based on this, today's spectrum analyzer can also be called vector signal analyzer (or real-time spectrum analyzer).
In the specific downstream application field, vector signal analyzer is widely used in satellite communication, radar, spectrum monitoring, semiconductor, new energy, artificial intelligence, Internet of Things, automotive electronics, medical electronics, aerospace and national defense, electronic countermeasures, education and scientific research and other industries.
Vector network analyzer
According to the industry standard "SJ/T11433-2012 General Specification for Vector Network Analyzers", the vector network analyzer is an instrument that can measure and analyze the S parameters of complex transmission and complex reflection, and can measure and analyze the S parameters of single-port, double-port or multi-port networks, and has the ability to calibrate and automatically correct errors according to the requirements of some error model.
Vector network analyzer combines spectrum analyzer technology, signal generator technology and vector network analysis technology. It is an essential testing and measuring instrument in the field of RF microwave, and it is also the basic form of special instruments in many industries.
The vector network analyzer will use its own signal generator to transmit signals to the tested parts, and then obtain the information attributes of the tested parts by analyzing the returned signals.
radio-frequency generator
The RF signal generator can generate RF signals of various frequencies with high spectral purity and stable frequency and amplitude. It can not only generate arbitrary waveform signals, but also up-convert arbitrary waveform signals into RF microwave signals. It is an essential equipment for R&D, manufacturing, maintaining and testing radio equipment and RF microwave devices. Its specific functions include vector modulation signal generation, electromagnetic compatibility, microwave signal generation, clock testing and security authentication. Widely distributed in communications, semiconductors, new energy, automotive electronics, medical electronics, consumer electronics, aerospace, education and scientific research and other industries.

-Three RF components promote the development of the downstream trillion-dollar market.
These three RF devices are complementary to downstream application development. Although the market scale of the three RF components is relatively small, the three RF products are the basic measuring equipment necessary for downstream application development.
The upgrading and development of products and technologies in downstream 5G communication, commercial aerospace, Internet of Things, semiconductors, millimeter-wave radar, satellite communication and other fields require higher-performance instruments to measure and test related indicators. The three RF products can be used for spectrum measurement and analysis, spectrum monitoring, modulation and demodulation, circuit network analysis, electromagnetic compatibility testing and so on. For complex signals, we can provide comprehensive measurement and test solutions for downstream applications with related software. Therefore, the three major RF products are typical "small caliber, big drive" products, and the improvement of technology and performance of the three major RF products will drive the rapid development of downstream industries.
In terms of typical downstream application market, in the field of Internet of Things, according to CCID statistics, the market scale of China Internet of Things reached 2.63 trillion yuan in 20021year; In the field of 5G, according to the statistics of China Information and Communication Research Institute, in 202 1 year, 5G directly boosted the economic aggregate 1.3 trillion yuan; In the field of semiconductors, according to the statistics of the Semiconductor Industry Association (SIA), in 202 1 year, the sales of China semiconductor industry reached192.5 billion US dollars; In the field of automotive electronics, according to the statistics of China Automobile Industry Association, the automotive electronics market in China reached 889.4 billion yuan in 20021year; In the field of satellite communication, according to the statistics of CCID Radio Management Institute, it is estimated that the market scale of China satellite communication industry will be around 90 billion yuan in 20021year.
In application scenarios, RF signal generator is an essential tool for measuring radio signals, especially high-frequency signals. Spectrum and vector network analyzer is mainly used in research and development, production testing, field maintenance, education and teaching. High-end products are mainly used for the development of high-performance RF devices, millimeter-wave communication systems and cutting-edge research.
From the specific application fields, the downstream application industries of the three RF components are basically the same, including semiconductors, consumer electronics, mobile communications, automotive electronics, autonomous driving, car networking, Internet of Things, national defense and aerospace, scientific research and education, etc. Among them, the accelerated development of several downstream application industries is expected to accelerate the demand for catalytic measuring instruments.
2. The competition pattern of the three major RF devices markets in China.
-product technology: domestic manufacturers have achieved high-end breakthroughs, and electrical technology and Chengdu Jin Jiu are in the first echelon.
In recent years, domestic manufacturers have achieved high-end breakthroughs in products. Domestic manufacturers of high-end products, such as Chengdu Jin Jiu, Electric Kesi Instruments, etc. All of them have exceeded 50GHz, and their products such as signal generator, signal analyzer and vector network analyzer can all benchmark the indicators of similar instruments of international first-line brands.
On the whole, in terms of the three major RF components, the technical level gap between domestic manufacturers and foreign manufacturers is not big, and some domestic manufacturers have certain strength to compare with foreign manufacturers horizontally.
From the product performance of specific enterprises, Electric Science Instrument represents the highest level of domestic manufacturers among the three RF products, followed by Chengdian Jin Jiu, and its three RF products are close to the highest level of domestic manufacturers.
According to the arrangement and analysis of domestic enterprises' product data manuals, enterprise announcements and other public materials, the competition patterns of the three major enterprises related to the RF market in China are divided on the technical level. Electrical Kesiyi and Chengdu Jin Jiu are in the first echelon of product performance, while Ding Yang Science and Technology, Puyuan Jingdian, Chuangyuan Instrument and Youlide are in the second echelon of product performance.
-Market layout: Domestic manufacturers have grasped the window period and basically achieved comprehensive coverage of high, medium and low-end markets.
On the market side, the global industrial chain reorganization brought by the COVID-19 epidemic has brought a window of opportunity for domestic manufacturers. Domestic manufacturers such as Puyuan Jingdian, Ding Yang Science and Technology, Youlide, etc. have raised funds through IPO in order to seize the opportunity window and further expand their influence in the domestic market.
After the breakthrough of localization in the high-end market monopolized by foreign manufacturers, domestic manufacturers such as Diankesiyi, Chengda Jin Jiu, Ding Yang Science and Technology, Puyuan Precision Power, etc. have basically achieved comprehensive coverage of the domestic high, medium and low-end markets.
-Market competition: the revenue of listed companies is growing rapidly, the status of domestic manufacturers is constantly improving, and the market for high-end products is broader.
In this paper, the companies that disclose three RF-related business data in the electronic measuring instrument industry are selected for summary analysis. Puyuan Precision Electric uses its RF instrument business income, Ding Yang Science and Technology uses its waveform and signal generator, spectrum and vector network analyzer business income, and Chuangyuan Instrument uses its signal analysis, spectrum analysis and vector network analysis business income.
Through summary, it is found that the business related to the three major RF components of the enterprise grows rapidly in 20 18-2020, and the income related to the three major RF components of the enterprise increases by 29.92% in 20 19 and 24.4 1% in 2020. At the same time, the proportion of the three major RF-related services selected by enterprises in China market is also increasing year by year. Based on the above data, to a certain extent, it shows that the market position of Chinese manufacturers in China market is constantly improving.
Note: Puyuan Jingdian and Ding Yang Science and Technology have not released the product breakdown data for the whole year of 20021,so the data of 20021here only include the data of related businesses of Puyuan Jingdian and Ding Yang Science and Technology in the first half of 20021.
According to Jost Sullivan's statistics and calculation data, in the entire electronic measuring instrument market in China, the total market share of foreign manufacturers such as Deco Technology, Roeder and Schwartz, Anli, Tektronix and Ricoh is about 40%. Because the high-end product market is almost monopolized by foreign manufacturers, it can be seen that the market share of foreign manufacturers is far above 40%.
The products of the above-mentioned listed companies are mainly located in the mid-range, but in addition, domestic enterprises that have achieved high-end breakthroughs, such as Diankesiyi and Chengda Jin Jiu, are not listed, and their signal generators, signal analyzers and vector network analyzers have exceeded 50GHz, all of which can benchmark the indicators of similar instruments of international first-line brands and become direct competitors of foreign manufacturers in the high-end product market in China. Therefore, there is extensive competition and domestic substitution in the field of high-end RF products.
3. China's three major RF domestic substitution paths: domestic substitution is the general trend, how can domestic manufacturers break the game?
-breaking through technical barriers
The technical core of RF signal generator, spectrum and vector network analyzer is mainly based on RF microwave circuit and digital signal processing. The main technical threshold of the product lies in RF microwave circuit design, digital signal analysis algorithm, software platform and so on. , involving many microwave electromagnetic waves and communication theories. The applied RF chip technology is complex, the cost is high, and the early research and development investment is large.
At the same time, with the rapid development of downstream application fields such as 5G communication, radar, Internet of Things, automotive electronics and satellite communication, the application range of frequency domain signal measurement is constantly expanding, and the downstream application fields put forward higher requirements for the performance of frequency domain measuring instruments. Therefore, to realize domestic substitution, it is necessary to break through the technical barriers of three high-end RF products. For example, when the product reaches the measuring frequency range of 26.5GHz, the design difficulty and cost of RF chip, RF material, RF connection, microwave simulation, micro-assembly circuit technology and other related technologies also increase rapidly. Therefore, the technical barriers of the three high-end RF products are high, and it is urgent to realize the self-control of high-end products.
Breaking through technical barriers means that a lot of manpower and funds need to be invested. Many domestic manufacturers have increased their investment and accelerated the pace of independent research and development. Chengdu Jin Jiu, for example, invested a lot of R&D personnel and R&D funds, of which R&D personnel accounted for 66% and R&D expenses accounted for 35%, ahead of other enterprises in the industry. The effect brought by this practice is also extremely remarkable. After years of technical accumulation, Chengdu Jin Jiu has broken the international technical barriers and developed a signal analyzer and signal generator by mastering four hard-core technologies: broadband ultra-wideband multi-channel signal generation and simulation technology, broadband high isolation excitation source and multi-channel signal separation and reception technology, broadband dynamic broadband signal reception and analysis technology and high-speed digital acquisition and processing technology.
-strive to build a brand.
In recent years, the Party and the state have attached great importance to brand building in China. Starting from 20 17, May 10 will be established as "China Brand Day" every year. Under the background of new era, new economy and new track, the importance of brand value to enterprises is beyond doubt. With the development of electronic information industry chain, the difficulty of domestic substitution of high-end scientific research instruments and technologies lies not only in technology, but also in the "trust" of the whole market.
The way to build domestic independent brands is to build industrial brands with Internet thinking. For example, since its birth, Chengdu Jin Jiu has positioned itself as a high-end technology, adhering to the humanistic spirit and long-term spirit of "one group of people, one thing, one heart, one life" and devoted itself to the research and development of high-end electronic testing and measuring instruments. In 2022, Chengdu Jin Jiu was also highly valued by the state and was selected as China Brand Day.
At the same time, under the normalization of epidemic prevention and control, domestic independent brands closely combine the characteristics of communication channels in the new era, innovate online and offline communication and promote domestic brands, and build their own brand positions.
-Pay attention to market cultivation and construction.
In the field of general electronic test and measurement instruments to which the three RF components belong, there are some dominant enterprises in Europe and America, such as Tektronix, Teck, Ricoh, Rod, Schwartz, etc. They have trained mature users, can skillfully understand and use the general electronic test and measurement instruments with increasingly complex functions, and can better identify the performance of products when selecting related instruments and choose some brands with high cost performance.
It can be seen that enterprises are particularly important for the cultivation and construction of market consumer habits, and are a powerful means to build a moat of markets and brands. For example, through insight into the consumption/usage habits of domestic customers, Chengdu Jin Jiu makes its products conform to the operating habits of domestic consumers from the perspective of market demand and usage habits, and does not need to adapt to new operating modes, thus greatly reducing the learning cost of product use; In addition, Chengdu Jin Jiu products have excellent expansibility and compatibility, which greatly reduces the construction cost of user-related product ecology. The above two methods are effective means and ways to realize domestic substitution quickly.
Another example is the "Tianhengxing" series products recently released by power companies, which have advantages in performance and function. "Tianhengxing" series products use high-definition large screen to present the measurement results, and various parameters are clear at a glance, and support multi-touch, custom control interface, "one-click search" and other functions, making the operation more concise and efficient.
4. Summary: China's market is developing rapidly, so it's just the right time for domestic substitution.
In recent years, the market scale of the three major domestic RF components has grown rapidly, further promoting the downstream trillion-dollar market. At the same time, domestic manufacturers have been promoted and developed in different degrees in market position and product performance, especially the gap in technical level has been further narrowed. On the whole, everything is ready, and it is only a matter of time before domestic substitution.
In terms of domestic substitution, different enterprises have chosen different implementation paths. Some enterprises pay attention to breaking through technical barriers, some enterprises devote themselves to brand building, some enterprises attach importance to market cultivation and construction, and some enterprises take a multi-pronged approach and embark on a sustainable development road of domestic substitution.
