Abstract
For CDMA/AMPS dual-mode cellular phones, a power amplifier operating a t 3.3 V has been developed for the first time. It consists of linear G aAs power MESFET's and an output matching circuit which reduces the se cond and the third harmonics. The amplifier shows an output power of 3 1.5 dBm and a power-added efficiency of 61% for AMPS mode. The third-o rder intermodulation distortion and the fifth-order one are measured t o be -32 dBc and -45 dBc at an output power of 26 dBm for CDMA mode.
