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 frequency 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 via advanced CNC machining in Taiwan, this ultra-compact 45 g adapter features a standardized square PBR Style flange interface with an integrated gasket groove for pressurization support, mated to a high-durability coaxial SMA-Female connector port featuring a passivated stainless steel build, safely managing continuous wave power loads up to 200 Watts (CW). This specialized layout makes it the definitive choice for laboratory RF measurements, satellite communication testing, advanced wireless networks, and mission-critical Signal Defense infrastructures.
