| Abstract |
In this paper designed J-class amplifier that have high efficiency using parasitic of pHEMT. Measured results of the designed J-class amplifier is maxmum output power of 31.5dBm and gain of 16.5dB, minimum output power of 29.8dBm. when input power 15dBm. Maxmum drain efficiency is 76.2% at 2.95GHz, maxmum drain efficiency is 61%. The J-class amplifier has average gain of 15.35dB and average efficiency of 35%. |
