Abstract :
A 240 W push-pull FET for the base stations of the third generation systems has been developed. The high gain and high efficiency performance and excellent DC behavior under high temperature of the FET chip contributes to realize such a high power operation. The developed FET achieved 240 W (53.8 dBm) output power, 12.0 dB linear gain and 50% power-added efficiency at 2.14 GHz. This is the highest output power device using GaAs FET technology ever reported
