Abstract :
A new design technique by an extended use of the load-pull method for a high efficiency and low distortion power amplifier in wide range of load impedances is proposed. A two stage GaAs MMIC power amplifier which meets the Japanese PHS standard with high efficiency and low distortion within load VSWR of 3 was designed by using this method.
