Description & Specification
WR-75 Waveguide to Coaxial Adapter
Precision X/Ku-Band Transition | 45g Ultra-Lightweight Cube | 10.0 GHz – 15.0 GHz
The WC-75-UBR-SF is a laboratory-grade 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 (covering upper X-band and lower Ku-band segments), 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 precision machining in Taiwan, this "Featherweight" 45 g adapter features an ultra-compact 38mm cubic layout mated to a precision coaxial SMA-Female connector port, safely managing continuous wave power loads up to 200 Watts (CW). This specialized layout makes it the definitive choice for weight-sensitive airborne radar assemblies, drone communications, portable VSAT terminals, wireless testing chambers, and mission-critical laboratory calibration setups.
