Abstract
The paper describes common issues faced designing GaAs HBT Power Amplifiers for 2G CDMA handsets & how to solve them. Common issues developed are non-linea noise performance, current consumption & ACPR at all power levels, Icq versus temperature, all related to the bias circuit. Then requirements more specific to 2.5G applications are explored, solutions for better Icq control, Efficiency and ACPR performance with temperature & power are proposed.
