A high efficiency power amplifier is implemented using a simplified design method. The approach utilizes small signal S-parameter data only. A high efficiency power amplifier with a maximum power added efficiency of 68.8 %, a nominal power gain of 8.6 dB and 21 dBm output power at 7.5 GHz was implemented. The high efficiency performance is obtained from proper selection of the second harmonic termination for a class AB power amplifier
