Microwave engineering

A device that taps a fixed fraction of signal power

In microwave and RF engineering a directional coupler is a passive four-port device that samples a defined fraction of the power travelling in one direction along a transmission line and delivers it to a coupled port, while ideally passing nothing from the reverse direction. Pozar's Microwave engineering sets out the coupling factor, directivity, and isolation that specify such couplers. The referent is a power-dividing network element, measured in decibels of coupling and directivity, and has nothing in common with a rail car's mechanical coupler beyond the word's meaning of joining two things.[1]
