A miniaturized GaAs power amplifier for 1.5 GHz digital cellular phones

An extremely miniaturized GaAs PA has been developed for the application in 1.5-GHz Japanese digital cellular phones. By using MuMIC (i.e. multilayer microwave integrated circuit) technology, the half sized (0.2 cc) PA with 1.1 W output power has successfully been implemented. The 48-% power-added efficiency has been obtained with drain supply voltage of 3.5-V.
