Abstract
A directional coupler for a wireless communication device includes a first input port, a first output port, a second input port, a second output port, and a coupled port. The first input port and the first output port are respectively configured to receive and provide a first signal to be transmitted from the wireless communication device. The second input port and the second output port are respectively configured to receive and provide a second signal to be transmitted from the wireless communication device. A coupled port is configured to selectively provide a coupled signal corresponding to each of, in respective modes, the first signal and the second signal.
