Fairview Microwave introduces its family of precision waveguide directional couplers. This release consists of 28 models covering a frequency range from 18 to 110GHz in seven popular frequency bands: K, Ka, Q, U, V, E and W.

Fairview Microwave’s waveguide couplers are available in waveguide sizes from WR-42 up to 18GHz all the way to WR-10 up to 110GHz. These directional couplers are offered with 10 or 20dB coupling values and have high directivity of 30dB typical with insertion loss is as low as 0.6dB in certain models. Fairview’s waveguide couplers are available in both standard and split block configurations and are also available in both E-bend and H-bend designs. They utilise a multi-hole design that provides optimal power reflection measurements and consistent performance.

Fairview’s MMW waveguide directional couplers are widely used in applications such as on-the-bench testing scenarios, radar systems, satellite communications, point-to-point backhaul, signal sampling and other general purpose applications in wireless transceivers. These waveguide couplers are constructed using high quality brass copper and are gold plated for added precision and accuracy.

“Our newest portfolio of waveguide directional couplers provide designers a comprehensive selection for MMW signal sampling and testing components when coaxial solutions are not possible,” explains Brian McCutcheon, Vice President and General Manager, Fairview Microwave. “We are committed to expanding our waveguide product lines to ensure we have the components needed by engineers as the industry continues to push towards higher and higher frequency applications.”
