Abstract
A Doherty amplifier system is disclosed. The Doherty amplifier system includes a carrier amplifier having a carrier input and a carrier output, and a peaking amplifier having a peaking input coupled to the carrier input and a peaking output coupled to the carrier output. Analog pre-distortion circuitry is configured to linearize the carrier amplifier and linearize the peaking amplifier by compensating for base-to-collector capacitance loading of the carrier amplifier and the peaking amplifier during operation.
