Description & Specification
WR-650 Waveguide to Coaxial Adapter
Precision L-Band Transition | Standard UDR Flange Layout | 1.14 GHz – 1.73 GHz
The WC-650-UDR-SF is a high-precision microwave Waveguide to Coaxial Adapter professionally engineered for strict adherence to the rectangular WR-650 architectural standard. Operating continuously across the 1.14 GHz to 1.73 GHz L-Band spectrum, 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 2.2 kg adapter features a standardized rectangular UDR Style (UG417A/U 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 pairing with standard gain horn antennas during radiation pattern tests, satellite tracking systems, aerospace radar calibration, and mission-critical RF measurement networks.
