Abstract

In this paper, 2-stage Power amplifier with external bias controller for\ulcorner IMT-2000 handsets was designed using SiGe HBT with excellent linearity to 1\ulcornereduce size and weight. The designed amplifier has 26.5 dBm output power, 33% power added efficiency, and 22 dB linear power gain in 1920-1980MHz frequency range.
