This paper presents the analysis and coherent design method of a high-efficiency broadband parallel-circuit Class-Epower amplifier with second harmonic control circuit. The PA’s broadband characteristic is achieved through analysis of the load network using double reactance compensation technique. Using a high power LDMOS transistor and operated from a 35 V supply voltage, the practical PA exhibits 41.5-44.1 dBm output power and 79-82.2% drain efficiency over 115-155 MHz frequency range. The measurement results show good agreements with the simulation results and theory.
