INVERTED DOHERTY POWER AMPLIFIER WITH LARGE RF FRACTIONAL AND INSTANTANEOUS BANDWIDTHS

Last updated:

Abstract:

Apparatus and methods for an inverted Doherty amplifier operating at gigahertz frequencies are described. RF fractional bandwidth and signal bandwidth may be increased over a conventional Doherty amplifier configuration when impedance-matching components and an impedance inverter in an output network of the inverted Doherty amplifier are designed based on characteristics of the main and peaking amplifier and asymmetry factor of the amplifier.
