Abstract
Aspects of this disclosure relate to a radio frequency coupler and a switch between a port of the radio frequency coupler and an adjustable termination impedance circuit. In an embodiment, an apparatus includes a radio frequency (RF) coupler, a termination impedance circuit, and a switch circuit. The RF coupler can provide an indication of forward RF power at a coupled port in a forward power state and provide an indication of reverse RF power at an isolated port in a reverse power state. The termination impedance circuit can provide an adjustable termination impedance. The switch circuit can electrically connect the termination impedance circuit to the isolated port in the forward power state and electrically isolate the termination impedance circuit from the isolated port of the RF coupler in the reverse power state.
