Abstract
With the rapid development of wireless communication technology,the demand for multi-band communication systems has been increasing in recent years.On this basis,a design method of dual-band power amplifier is proposed,and a GaN based P/S band dual frequency power amplifier is designed.In this amplifier,inter-stage matching network(ISMN)and input matching network(IMN)are used to realize dual-band function of power amplifier.The output matching network(OMN)is designed by means of the theory of capacitor self-resonance,which provides a short circuit point for the power amplifier signal,thus achieving the stable operation of the circuit in the dual-band.The simulation results show that when the frequency is the P band,the small-signal gain of the amplifier is greater than 29.4 dB,the saturation output power(Psat)is greater than 40.2 dBm,and the power additional efficiency(PAE)is 62%to 66.2%;when the frequency is S band,the amplifier has a small signal gain greater than 29.7 dB,a saturation output power of more than 39.1 dBm,and a PAE of 52.3%to 66.3%.关键词
