Abstract

A Doherty power amplifier (DPA) with collector current and voltage controls for CDMA and WCDMA |(W)CDMA| application has been investigated and implemented using a standard HBT process. The impact of bias of the peak amplifier on linearity is also discussed. The statistical average current is used to evaluate the current consumption improvement of the DPA with collector current and voltage controls as compared to a single-ended class AB power amplifier.
