A wideband power amplifier for a frequency hopping radio unit is designed. To obtain higher efficiency, it is designed for the Class B mode overdrived. The broadband transformer and feedback circuits are adapted to obtain broadband characteristics. The designed amplifier is simulated using the ADS, which is a CAD software from HPEEsof, Simulation results of the designed amplifier are well suited for the design specifications. The designed amplifier are fabricated. Measured results of the fabricated amplifier well agreed with the simulation results and are in good agreement with the predicted performance
