Description & Specification
WR-137 Waveguide to Coaxial Adapter
Precision C-Band Transition | Pressurizable PDR Flange | 5.85 GHz – 8.2 GHz
The WC-137-PDR-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 compact 145 g adapter features a standardized rectangular PDR Style flange interface with an integrated gasket groove for pressurization support, mated to a precision coaxial N-Female connector port with a durable structural layout, safely managing continuous wave power loads up to 300 Watts (CW). This specialized configuration serves as the native coaxial feed architecture for manufacturing the HS-137 series standard gain horn antennas, making it the definitive choice for satellite uplinks, maritime data networks, weather radar arrays, and critical laboratory calibration setups.

HS-137 Series Core
The native transition block explicitly tuned for manufacturing the HS-137 Standard Gain Horn Antenna catalog, guaranteeing absolute mechanical concentricity and flawless electrical boresight alignment parameters.
C-Band Reliability
Seamlessly spans the core 5.85 to 8.2 GHz spectrum, supplying the unwavering electromechanical adaptation factor necessary for commercial and military satellite communication uplinks.
Taiwanese Engineering Excellence
Precision designed and manufactured in Taiwan under strict industrial quality control standards, ensuring consistent internal launcher dimensions, absolute flat positioning alignment, and calibration constancy.
Signal Efficiency
Maintains a rigorous maximum reflection threshold of 1.25 VSWR, maximizing link power scaling factors by eliminating signal path energy choke points.
PDR Flange Interface
Features a standardized rectangular PDR style interface complete with a precision gasket seat routing, matching requirements for pressurized gas or weatherized containment feeds.
Lightweight Integration
At an optimized 145 g form factor, it minimizes structural bending moment loads on complex boom-mount feeds, horn nodes, and sensitive laboratory polarization controllers.
