Description & Specification
WR-90 Waveguide Coaxial Adapter
Precision X-Band Transition | Standard UG-39/U Flange | 8.2 GHz – 12.4 GHz
The WC-090-PBR-SF is a high-precision microwave Waveguide to Coaxial Adapter professionally engineered for strict adherence to the standard WR-90 architectural layout. Operating continuously across the 8.2 GHz to 12.4 GHz X-Band spectrum, this premium adapter enables high-efficiency signal transition between rectangular waveguide systems and coaxial networks. Featuring a standardized UG-39/U (PBR Type) flange interface and a precision coaxial SMA-Female connector, it delivers flawless Signal Integrity with an exceptionally low maximum VSWR profile of 1.3 : 1. Fully designed and manufactured in Taiwan, this ultra-lightweight 35g component safely manages continuous wave power loads up to 250 Watts (CW), rendering it the definitive choice for professional radar systems, satellite ground stations, advanced wireless testing networks, and mission-critical Signal Defense calibration arrays.
