Abstract

Wireless circuitry may be provided with amplifier circuitry that includes a set of amplifiers on first and second signal lines and matching circuitry that couples the set of amplifiers to an output. The matching circuitry may include a transformer having a primary winding that extends between the signal lines and a secondary winding that extends between the output and a first terminal. The matching circuitry may include first and second capacitors coupled between the signal lines. The amplifier circuitry may be operable in a full power mode and a reduced power mode. The matching circuitry may include a first switch coupled between the first and second capacitors, a second switch that couples the first terminal to ground, and a third switch that couples a second terminal on the secondary winding to ground. The first, second, and third switches may be adjusted between the full and reduced power modes.
