Waveguide Directional Couplers
Fairview Microwave’s waveguide couplers are offered in various waveguide sizes from WR-42 (K band) to WR-10 (W band) and operate up to 110 GHz. These are instrumentation-grade directional waveguide couplers that are offered in both 10 dB and 20 dB coupling values.
High directivity of 30 dB is typical and insertion loss is as low as 0.6 dB in some models. Fairview’s waveguide directional couplers are available in both standard and split block designs and can be ordered in E-Bend and H-Bend configurations. All of Fairview’s waveguide components are in-stock and available to ship the same day.
