Essential qualities of RF engineer: 1. Basically, all RF equipment is foreign. Theoretical basis. From low frequency to high frequency to electromagnetic field to communication system

As a RF engineer in the communication industry, I mainly need to be familiar with the design of RF circuits, to be precise? ? It is the knowledge of high-frequency circuits, such as mixer circuits, phase-locked loop circuits, power amplifier circuits and low-noise amplifier circuits. His main works include RF circuit design theory and application, RF communication circuit, microwave technology foundation, etc. You can complete the introductory textbook 3. A lot of practical experience. Including (1) familiarity with the equipment; (2) actual circuit debugging ability; (3) familiarity with the instrument; (4) Understanding of various indicators, such as gsm or wcdma, and product performance, so it seems that the requirements for an RF engineer are still relatively high. In fact, it is a trend that equipment will become more integrated in the future, and all engineers must face this change. The difference between RF and baseband is that the former focuses on communication system, while the latter focuses on application. Radio frequencies can be limited to wireless and mobile areas. If it is wired, the knowledge of RF is limited to EMC. As long as the future communication system continues to expand in wireless, mobile and bandwidth, the knowledge of RF engineers will not fail. In fact, for RF engineers, the change of device integration is that the actual circuit debugging ability does not need to be as strong as before. But in other words, these jobs are all done by IC engineers, but the people who can contact IC engineers are RF application engineers with RF background. It is nothing more than being in a mobile phone company now, and you can still find your place in a chip design company in the future. The future development trend of RF is to integrate high-speed AD and DA on one chip to realize the current RF circuit. The work of RF personnel is simplified to using RF instruments to test those RF indicators, which can be completed by hardware engineers. They should find a new way out Therefore, in order to become a qualified RF personnel, we must first learn the basic knowledge of analog circuits in a down-to-earth manner.

Circuit, electromagnetic field theory and communication principle (based on signals and systems and random processes) are the most important.

Radio frequency engineers have a good prospect, because mobile and wireless will be the main theme of communication in the next 20 years. Of course, being an excellent RF engineer requires a lot of efforts, and the most important thing is experience, which is different from that of a digital engineer. Among them, RFIC engineers are particularly popular, and the salary of recent graduates should be around 80 thousand a year. Radio frequency engineers can change their own industries by learning common software for chip design and getting familiar with chip knowledge. ;
