The FMW28CP005-40 is a WR-28 Directional Broadwall waveguide coupler with2.92mm female coupled port that operates in the frequency range of 26.5 to 40GHz. This Waveguide component has a maximum VSWR of 1.5:1. These designsare made of painted copper alloy and incorporate a broad wall configuration thatresult in a mid-band nominal coupling value of 10, 20, 30, 40 or 50 dB. Commonapplications for this component would be where power measurements arerequired within a system for measuring/sampling power or frequency monitoringwith minimal signal loss to the main transmission line. Fairview Microwave offersa complete family of waveguide Crossguide and Broadwall couplers that are instock and ship same day.
