WR-137 Waveguide to Coaxial Adapter

Precision C-Band Transition | Standard PAR Flange Layout | 5.85 GHz – 8.2 GHz
The WC-137-PAR-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 160 g adapter features a standardized rectangular PAR Style (CPR-137 compatible) flange interface, mated to a precision coaxial N-Female connector port, safely managing continuous wave power loads up to 300 Watts (CW). This 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.
