Abstract :
In this letter, a Class-F power amplifier with high power added efficiency (PAE) is reported. The novel load network satisfies the optimum load resistance at fundamental frequency, second and third harmonics. The optimum value of the circuit parameters is obtained by harmonic balanced analysis at drain voltage 3.1 V. The results show that proposed PA at 2.4 GHz achieved the PAE of approximately 80% at 23.6 dBm output power for single stage pHEMT.
