Abstract(in English) | This paper describes 0.2cc HBT power amplifier module for W-CDMA systems which have been receiving lots of attention as the next generation mobile communication standard. The W-CDMA systems require lower adjacent channel leakage power than the 2nd generation systems such as PDC, IS-95, due to its high data transmission rate and tight space of the adjacent channel. With high performance InGaP / GaAs HBT (Heterojunction Bipolar Transistor) and a phase distortion cancellation technique between driver stage and power stage in a two-stage amplifier, the module achieved a high PAE of 40.2% and a low ACP of -40.8 dBc at a 28 dBm output power for W-CDMA modulation scheme. |
