Abstract :
The present paper provides design techniques for highly efficient microwave power amplifiers driven by low voltage power supplies. Main power amplifier design variables, such as conduction angle and fundamental and harmonic load impedance terminations, are studied, to enable the selection of the optimum parameter set under small voltage operating conditions. Theoretical predicted conclusions are then validated with a practical S-band GaAs monolithic microwave integrated circuit, MMIC, class-F power amplifier
