Directional Coupler

Directional couplers have the coupling line parallel to the main line and are typically connected broad wall  to broad wall. They are usually offered as a 3 port device, with an internal matched load at port 4, nullifying signal from port 2  to 4.

Sylatech’s High Directivity couplers are suitable for applications involving reflectometry, signal injection, power sampling and local oscillators. We offer a standard range of devices for waveguide sizes WG14 to WG22 (WR137 to WR28) and we also offer double ridge products on request.

The couplers are designed using a multi hole method conforming to a Tschebyscheff array which offer superior performance in terms of coupling variation over band (CVOB) where the bandwidth is the entire waveguide band. Coupling values from 10 dB to 50 dB can be realised with good directivity and a typical mainline VSWR of 1.1:1.
