Sumitomo – High Power GaAs FET Amplifiers: Push-Pull versus Balanced Configurations

Abstract:
Various methods of combining high power “push-pull” devices are often possible. Two methods, push-pull and balanced configurations, are theoretically discussed. A practical example with a push-pull and a balanced amplifier using the same 150 W, S-band GaAs device(1) is reported and amplifier data are compared and analyzed.
