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.
Claims25
A circuit comprising:
- a first directional coupler comprising a first input port, a first transmitted port, a first isolated port and a first coupled port, the first directional coupler disposed on a first substrate;
- and
- 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, wherein the first direction select switch is disposed on the first substrate along with the directional coupler.
A circuit comprising:
- a first directional coupler comprising a first input port, a first transmitted port, a first isolated port and a first coupled port, the first directional coupler disposed on a first substrate;
- and
- a second directional coupler comprising a second input port, a second transmitted port, a second isolated port and a second coupled port, the second directional coupler disposed on the first substrate;
- and
- a commutation switch having a first commutation input coupled to the first isolated port, a second commutation input coupled to the first coupled port, a third commutation input coupled to the second isolated port and a fourth commutation input coupled to the second coupled port, the commutation switch being disposed on the first substrate, and a commutation output port.
A method of operating a circuit comprising a first directional coupler having a first input port, a first transmitted port, a first isolated port and a first coupled port, and 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, wherein the first directional coupler and the first direction select switch are disposed on a same substrate, and the method comprises:
- in a first state, coupling the first isolated port to the first switch output port comprising placing a first switch of the first direction select switch in a first position;
- and
- in a second state, coupling the first coupled port to the first switch output comprising placing the first switch of the first direction select switch in a second position.
