Description

This paper studies and designs a gain controllable radio frequency amplifier system. As the hardware core of the whole system, the variable gain amplifier realizes the data function of the amplifier combined with the single chip microcomputer. After adjusting the gain of RF amplifier, the input signal can be amplified or attenuated, and the ideal output signal can be obtained. Using ADS simulation, the gain controllable RF amplifier system designed in this paper has better control effect, meets higher index, and has stable performance. The experiment shows that the gain controllable RF amplifier system has certain practicability.
