Abstract
In accordance with an embodiment, a circuit includes a first directional coupler comprising a first input port, a first transmitted port, a first isolated port and a first coupled port, where the first directional coupler disposed on a first substrate. The circuit also includes a first direction select switch having a first switch input port coupled to the first isolated port, a second switch input port coupled to the first coupled port, and a first switch output port, where the first direction select switch is disposed on the first substrate along with the directional coupler.
