The WC-975-UDR-SF is an industrial-grade microwave Waveguide to Coaxial Adapter professionally engineered for strict compliance with the large-format WR-975 rectangular waveguide architectural standard. Operating continuously across the 750 MHz to 1150 MHz frequency spectrum, this premium transition component ensures stable electromechanical coupling and maximum energy transfer with an optimized low return loss profile. Manufactured from high-grade aluminum alloy in Taiwan, this robust 4.0 kg adapter features a standardized rectangular UDR Style (CPR-975 compatible) flange interface mated to a precision coaxial SMA-Female connector port with a durable stainless steel build, safely managing continuous wave power loads up to 600 Watts (CW). This specialized layout makes it the definitive choice for driving standard gain horn antennas during radiation pattern tests, long-range radar tracking, satellite ground links, and industrial microwave sub-systems where mechanical rigidity and thermal stability are critical parameters.
