Abstract
Aspects of this disclosure relate to a radio frequency coupler with a decoupled state. In an embodiment, an apparatus includes a radio frequency coupler and a switch network. The radio frequency coupler has at least a power input port, a power output port, a coupled port, and an isolated port. The switch network can electrically connect a termination impedance to the isolated port in the first state, and the switch network can decouple an RF signal traveling between the power input port and the power output port from the isolated port and the coupled port in a second state.
