Description & Specification
WR-284 Waveguide to Coaxial Adapter
Precision S-Band Transition | Standard UDR Flange Layout | 2.6 GHz – 3.95 GHz
The WC-284-UDR-NF is a high-precision microwave Waveguide to Coaxial Adapter professionally engineered for strict adherence to the rectangular WR-284 architectural standard. Operating continuously across the 2.6 GHz to 3.95 GHz S-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 430 g adapter features a standardized rectangular UDR Style (PDR/CPR284 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 professional S-band radar system calibration, antenna measurement ranges, wireless testing chambers, and high-fidelity laboratory verification setups.
