A new envelope predistortion linearization architecture for handset power amplifiers

Abstract

The paper proposes a new envelope predistortion linearization architecture that utilizes low power analog components to correct intermodulation distortion (IMD) in RF power amplifiers (PAs). Log amps and phase detectors are used at the input and output of the PA to estimate the instantaneous complex gain. The outputs of the log amps and phase detector are… (More)
