The term hybrid coupler originally applied to 3 dB coupled-line directional couplers, that is, directional couplers in which the two outputs are each half the input power. This synonymously meant a quadrature 3 dB coupler with outputs 90° out of phase. Now any matched 4-port with isolated arms and equal power division is called a hybrid or ...
Picture shows a typical output expected from a Wilkinson power divider. The , are almost -3 dB, and the is low near the design frequency. Picture demonstrates a very high isolation between output ports (port 2 & 3) of a Wilkinson power divider
A rat-race coupler, also known as a hybrid ring coupler, is a type of coupler used in RF and microwave systems. In its simplest form, it is a 3 dB coupler and is thus an alternative to a magic tee .
English: Diagram showing how a 3 dB hybrid power divider can be used to combine powers at 90° phase difference. Date: 4 June 2011: Source: Self created using Inkscape:
The device has input ports (the beam ports) to which power is applied, and output ports (the element ports) to which antenna elements are connected. The Butler matrix feeds power to the elements with a progressive phase difference between elements such that the beam of radio transmission is in the desired direction.

Hybrid ring, used to produce sum and difference signals. A directional coupler which splits power equally between the output and coupled ports (a 3 dB coupler) is called a hybrid. [44] Although "hybrid" originally referred to a hybrid transformer (a lumped device used in telephones), it
