Abstract
In accordance with an embodiment, a directional coupler includes a coupler circuit and at least one amplifier coupled between a coupler circuit isolated port and a directional coupler isolated port and/or between a coupler circuit coupled port and a directional coupler coupled port. In various embodiments, the directional coupler is disposed over and/or in a substrate.
Claims26
A directional coupler comprising:
- a coupler circuit;
- and
- at least one amplifier coupled between a coupler circuit isolated port and a directional coupler isolated port and/or between a coupler circuit coupled port and a directional coupler coupled port, wherein the directional coupler is disposed over and/or in a substrate.
A directional coupler including a directional coupler input port, a directional coupler transmit port and a directional coupler output port, the directional coupler comprising:
- a coupler circuit including a first coupler circuit input port, a first coupler circuit transmit port, a first coupler circuit isolated port and a first coupler circuit coupled port;
- an amplifier coupled to the directional coupler output port;
- and
- a switch selectively coupling the amplifier to the coupler circuit coupled port and coupler circuit isolated port, wherein the directional coupler is disposed over and/or in a substrate.
A method of operating a directional coupler including a coupler circuit, and at least one amplifier coupled between a coupler circuit isolated port and a directional coupler isolated port and/or between a coupler circuit coupled port and a directional coupler coupled port, the method comprising:
- receiving an incident signal at a directional coupler input port coupled to a coupler circuit input port;
- transmitting the incident signal at a directional coupler transmit port coupled to a coupler circuit transmit port;
- and
- monitoring at least one signal at the directional coupler coupled port and/or the directional coupler isolated port.
