Optimal Design of RF Signal Power Amplifier Circuit

With the increasing requirement of wireless communication system, how to reduce signal distortion effectively and improve the received signal gain of the system has become an important problem to be solved in the design of RF power amplifier. In this paper, an optimization circuit of RF signal power amplifier matching network was designed based on AFT27S006N power transistor. The input and output of the AFT27S006N power transistor were matched respectively. The simulation results show that the gain of the circuit is 15.669dB when the circuit were not matched, and the gain of the circuit is 20.129dB after the matching optimization of the circuit, and the gain of the circuit is significantly increased by about 4.46dB.
