Abstract
An electronic device may include wireless circuitry with a transmission line path coupled between a transceiver and antenna. An amplifier may be disposed on the transmission line path. The amplifier may have a reconfigurable matching network at its output. The network may have coupled lines such as transmission line segments or transformer coils. The coupled lines may couple an input port of the network to a load port and a control port of the network. The load port may be coupled to the antenna. The control port may be coupled to an adjustable termination. The control port may receive a control signal that configures the adjustable termination to exhibit an impedance selected based on a VSWR of the antenna. The impedance of the adjustable termination may be tuned so the amplifier sees a consistent load impedance at the load port even as the VSWR of the antenna changes over time.
