This paper describes the design of 3-8 GHz super broadband and high power microwave power amplifier .The design uses bonding wires connecting the die and microstrip .The bonding wire connecting portion is simulated by HFSS .Gradual changes microstrip is used to achieve broadband matching in this paper.A high-power broadband amplifier is simulated and designed by co-simulation of ADS and HFSS . Simulation results show P1dB of 48 dBm, Psat of 49.5 dBm and Gain of 8.5 ±1 dB in the frequency range of 3-8 GHz.
