The WC-75-PBR-NF is a high-precision microwave Waveguide to Coaxial Adapter professionally engineered for strict adherence to the rectangular WR-75 architectural standard. Operating continuously across the 10.0 GHz to 15.0 GHz spectrum (overlapping upper X-band and core Ku-band applications), this premium transition component ensures stable electromechanical coupling and maximum energy transfer with an exceptionally low nominal V.S.W.R profile of 1.25 : 1. Manufactured from high-grade aluminum alloy in Taiwan, this robust 70 g adapter features a standardized rectangular PBR Style flange interface with an integrated gasket groove for pressurization support, mated to a high-durability coaxial N-Female connector port featuring a passivated stainless steel build, safely managing continuous wave power loads up to 300 Watts (CW). This specialized layout makes it the definitive choice for satellite communication testing platforms, laboratory RF measurements, advanced wireless networks, and mission-critical Signal Defense subsystems.
