Design of High-precision Control System for Amplifier

Power amplifier is one of the core components of the transmitter, and its power output efficiency directly affects the power output efficiency of the transmitter system, determines the propagation distance of the radiated wave signals, and has a critical impact on the performance of the transmitter system. However, the current transmitter is unstable due to its own output power, which is easy to cause communication link instability, poor communication performance and damage to the amplifier and other problems. In view of these problems, it is proposed to design a high-precision power output control system for power amplifiers by optimizing the algorithms of transmitter power detection unit and transmitter DSP unit, which can effectively improve the problems of output power stability and control accuracy in the use of the existing power amplifiers and improve the communication performance.
