Abstract :
A 150 W power FET for W-CDMA base stations has been developed. This FET combines four enhancement-mode (E-mode) 40 W FET chips newly developed and implemented in a package in a push-pull configuration. A saturation power of 51.8 dBm (150 W) and an associated 12 dB linear gain were achieved with this device at 2.2 GHz. A third order intermodulation distortion (IM3) obtained at the average output power of 47 dBm was as small as -36 dBc, providing a power added efficiency (PAE) of 35%.
