Sidewall and top wall couplers are two pieces of coplanar waveguide adjacent to each other which have had slots cut in the mutual wall. When the coupling value of these is set to 3dB they are described as hybrid couplers as there is no coupling variation over the band at this value.

Sylatech’s sidewall and topwall couplers are suitable for a wide variety of applications, including monopulse comparators, power dividers/combiners and balanced mixers. We offer standard range devices for waveguide sizes WG6 to WG22 (WR650 to WR28) with coupling values from 1.5 to 12dB. Devices are offered with a choice of socket or flanges to suit application and have typical VSWR of 1.1:1.
