Abstract

Aspects relate to a radio frequency (RF) coupler with a multi-section coupled line. One examples of an apparatus includes a RF coupler having at least a power input port, a coupled port and an isolated port, the RF coupler configured to provide an indication of forward RF power of an RF input signal at the coupled port in a forward power state and an indication of reverse RF power of the RF signal at the isolated port in a reverse power state, a termination impedance circuit configured to provide an adjustable termination impedance, and a switch circuit configured to electrically connect the termination impedance circuit to the isolated port in the forward power state and to electrically isolate the termination impedance circuit from the isolated port of the RF coupler in the reverse power state. Another example of an apparatus includes an RF coupler that includes a power input port, a power output port, a coupled port, a multi-section coupled line, and a switch configured to adjust an effective length of the multi-section coupled line electrically connected to the coupled port.
