Abstract

The invention relates to a system and a method for a directional coupler module. 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.

Description

[0001] This application claims priority to US Provisional Patent Application No. 62 / 049,763, filed September 12, 2014, entitled "System and Method for directional Coupler Module," the entire contents of which are hereby incorporated by reference. technical field [0002] The present application relates generally to electronics, and more particularly to a system and method for a directional coupler module. Background technique [0003] Directional couplers, which are electronic devices that can detect power transmitted in a specific direction, are widely used in various radio frequency (RF) circuits. For example, directional couplers can be used in radar systems to detect reflected waves by separating them, or in circuits that measure impedance mismatches in transmission lines. Functionally, a directional coupler has a forward transmission path and a coupled transmission path. The forward transmission path is usually low loss, and the coupled transmission path couples a port...
