Power dividers and directional couplers - Wikipedia
WEBA directional coupler designed to split power equally between two ports is called a hybrid coupler. Directional couplers are most frequently constructed from two coupled transmission lines set close enough together such that energy passing through one is coupled to the other.
Directional Couplers: Their Operation and Application
WEBOct 23, 2020 · Directional couplers are an important type of signal processing device. Their basic function is to sample RF signals at a predetermined degree of coupling, with high isolation between the signal ports and the sampled ports — which supports analysis, measurement and processing for many applications.
Microwaves101 | Directional Couplers
WEBDirectional couplers are four-port circuits where one port is isolated from the input port. Directional couplers are passive reciprocal networks, which you can read more about on our page on basic network theory. All four ports are (ideally) matched, and the circuit is (ideally) lossless.
What is a Directional Coupler? | Directional Coupler Primer
WEBA directional coupler designed to split power equally between two ports is called a hybrid coupler. In designing directional couplers for practical bandwidths, computer modeling and attention to design details help minimize causes of signal loss.

WEBMay 22, 2022 · Directional couplers are used to sample a traveling wave on one line and to induce a usually much smaller image of the wave on another line. That is, the forward- and backward-traveling waves are separated.
Connectorized Products : Directional Couplers
WEBDirectional Couplers allow power to be sampled from a transmission line with selectivity in one direction, discriminating between forward and backward signals. Directivity is the most important factor in selecting a directional coupler, with other important factors including return loss, coupling value, coupling flatness, insertion loss, and power handling.
