17.7 - 23.55GHz Passive Devices RF & Microwave Couplers Used To Sample High Frequency Signals
RF Microwave Couplers Introduction
A Directional coupler is a device that samples a small amount of Microwave power for measurement purposes. The power measurements include incident power, reflected power, VSWR values, etc.
Directional Coupler is a 4-port waveguide junction consisting of a primary main waveguide and a secondary auxiliary waveguide. The following figure shows the image of a directional coupler.
