Sidewall and Topwall Couplers

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 [...]

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 [...]

Crossguide

Sylatech’s crossguide couplers are suitable for applications requiring coupling across large bandwidths. We offer a range of standard devices for waveguide sizes ranging from WG10 to WG23 (WR284 to WR22). Typical designs have coupling values of 30dB or 40dB coupling variation over band (CVOB) of +/- 0.5 dB (15% bandwidth) and directivity greater than 25dB. [...]

OMTs

Our OMTs range from WG10 (WR284) to WG23 (WR22) and with a typical isolation of better than 40dB. They can be configured for left hand or Right hand circular polarisation.  Custom designs can also be accommodated. Please contact our sales team for details of our designs and to discuss your requirements. [...]
