The Waveguide Solution offers a range of Directional Broad Wall, Side Wall and Cross Guide Couplers in 3 and 4 port configurations. All couplers have been designed to offer low VSWR, flat response and high directivity over the entire designated waveguide band. Improvements in directivity and coupling value tolerances can be made for specified narrow band applications. The CC and DC series of couplers are designed, tested and manufactured to the highest quality standards. Couplers are manufactured with the full range of International Flange Style as shown in the The Waveguide Solution Flange Catalogue with alternative plated finishes on request. All The Waveguide Solution couplers are offered with an attractive, hard wearing, epoxy paint finish.
