Description & Specification
WR-137 Waveguide to Coaxial Adapter
Precision C-Band Transition | Standard UAR Flange Layout | 5.85 GHz – 8.2 GHz
The WC-137-UAR-NF is a high-precision microwave Waveguide to Coaxial Adapter professionally engineered for strict adherence to the rectangular WR-137 architectural standard. Operating continuously across the 5.85 GHz to 8.2 GHz C-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 170 g adapter features a standardized rectangular UAR Style flat cover flange interface, mated to a precision coaxial N-Female connector port, safely managing continuous wave power loads up to 300 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, serving as the core native transition block utilized to manufacture our elite HS-137 series horn arrays.
