| Abstract: | The microwave power amplifier is the key component in communication system.In this paper,the design method of microwave power amplifier for 3.55GHz W-CDMA base station was described based on EDA.The simulation was made according to the nonlinear model offered by the manufacturer.The bias was determined by DC simulation.The optimal source and load impedances were found with load-pull technology.Then the input-output matching network was designed.The test of the whole system indicate that this amplifier possesses high output power and better efficiency,which is applicable for linear base station. |
