Abstract
Doherty power amplifier with tunable input network. An input network for a Doherty power amplifier can include a splitter circuit configured to receive a radio-frequency (RF) signal and split the RF signal into a first portion along a first path to a carrier amplifier of the Doherty power amplifier and a second portion along a second path to a peaking amplifier of the Doherty power amplifier. The input network can further include a tunable input circuit implemented along either or both of the first path and second path. The tunable input circuit can be configured to provide control of the amplitude and phase of either or both of the first portion and second portion.
