PROJECT TITLE :

Wideband phase inverter integrated in Doherty power amplifier for linearity improvement

ABSTRACT:

A wideband phase inverter (WPI) integerated in a very Doherty power amplifier (DPA) is proposed for linearity improvement. This WPI is integrated at the output of the carrier amplifier within the DPA whereas keeping the identical size as the conventional DPA. The input signal is happy at both the carrier and therefore the peaking amplifiers and then the amplified signals are combined by the push-pull toplogy. This results in the cancellation of the even-order harmonic terms still as the cancellation of IMD3 by correct bias selection. An experiment shows the peak power-added potency (PAE) is around fifty% at 21 dBm output power with linearity improvement as the adjacent channel leakage ratio (ACLR) under a wideband code division multiple access signal is around -40 dBc. This improves around seven dB in ACLR under the same output power and PAE and better error vector magnitude (EVM) compared with the single-stage class AB amplifier.
