Fairview Microwave now offers a line of cross guide waveguide couplers with 4-ports, 3-ports and 2-ports with coax interfaces that work across C to K bands. Typical applications include test benches, instrumentation, product development and characterization.
The line is made up of 160 parts in three sub-categories: cross guide couplers (4 waveguide ports), cross guide couplers with terminations (3 waveguide ports) and cross guide couplers with terminations and waveguide to coax adapters (2 waveguide ports with either an SMA, Type-N or 2.92 mm coaxial connector). These couplers are constructed with bronze waveguide bodies and are offered with EIA (CPR)-style flanges or UG-style flanges per military standard. They cover eight waveguide bands in the 5.85 GHz to 33 GHz frequency range and are available with coupling factors from 20 to 50 dB. For detailed information and specs, peruse the datasheet.
