Microwave double-pole double-throw switch and microwave divide/through switch and power amplifier using thereof

Abstract

A highly efficient power amplifier is composed of (1) two microwave divide/through switches, (2) two power amplifiers, connected with the two microwave divide/through switches, to amplify the signal power transmitted from the first microwave divide/through switch, and (3) a half-wavelength transformer, connected to an output terminal of one of the power amplifiers, to delay the phase of the amplified signal by a half-wavelength.
