DIRECTIONAL COUPLER

Domain	Definition
Computing	Directional coupler (tap) A passive device used in cable systems to divide and combine radio frequency signals. A directional coupler has at least three ports: line in, line out, and the tap. The signal passes between line in and line out ports with loss referred to as the insertion loss. A small portion of the signal power applied to the line in port passes to the tap port. A signal applied to the tap port is passed to the line in port less the tap attenuation value. The tap signals are isolated from the line out port to prevent reflections. A signal applied to the line out port passes to the line in port and is isolated from the tap port. Some devices provide more than one tap output line (multi-taps). (1995-12-23). Source: The Free On-line Dictionary of Computing.
Electrical Engineering	A device that couples a secondary system only to a wave travelling in a particular direction in a primary transmission system, while completely ignoring a wave travelling in the opposite direction ; a coupling between a plurality of waveguides so designed as to guide energy along selected paths by the effect of phase differences between wave components.

Specialty Definition: Directional coupler

In telecommunication, a directional coupler is a transmission coupling device for separately sampling (through a known coupling loss) either the forward (incident) or the backward (reflected) wave in a transmission line.

Note: A directional coupler may be used to sample either a forward or backward wave in a transmission line. A unidirectional coupler has available terminals or connections for sampling only one direction of transmission; a bidirectional coupler has available terminals for sampling both directions.
