Abstract

A constant voltage/constant current (CV/CC) parallel operation heterojunction bipolar transistor (HBT) power amplifier (PA) configuration is presented, and its design method is described. A resistor base feed (CC mode) HBT is connected to an inductor base feed (CV mode) HBT in parallel, and compensates the gain expansion of the CV mode HBT due to near class-B operation. By adding CC mode HBT, the total quiescent current can be decreased from 32mA to 23mA with adjacent channel leakage power ratio (ACPR) < -40.0 dBc. At the maximum output power region, the fabricated PA achieves output power (P_out) of 26.8 dBm and power added efficiency (PAE) of 42.0% with ACPR of -40.0 dBc, and shows the comparable performances with a conventional PA using CV mode HBT.
