About this document

Doherty RF Amplifier Efficiency Analysis by Jose Antonio Garcia Perez is a document available to read on EtoBox.

This document summarizes the Doherty power amplifier system, which combines the outputs of two or more linear RF power amplifiers through an impedance-inverting coupler to improve efficiency. At low output levels, one amplifier operates linearly while the other is cut off. At higher outputs, the first amplifier remains saturated and acts as a voltage source while the second operates linearly and acts as a controlled current source. This allows the system to maintain high efficiency over a wide range of outp
