Description & Specification
WR-42 Waveguide to Coaxial Adapter
Precision K-Band Transition | Standard UG-595/U Flange | 18.0 GHz – 26.5 GHz
This precision-engineered WR-42 Waveguide to Coaxial Adapter provides a seamless, high-fidelity transition between rectangular waveguide paths and coaxial networks within the 18.0 GHz to 26.5 GHz K-Band spectrum. Optimized for high-frequency signal processing networks, professional 5G testing, satellite link characterization, and millimetric laboratory instrumentation, this premium adapter ensures stable electromechanical coupling and maximum energy transfer with an exceptionally low maximum V.S.W.R profile of 1.25 : 1. Fully designed and manufactured in Taiwan, this ultra-lightweight 30g component features a standardized square UG-595/U flange interface mated to a precision-grade SMA-Female connector with a robust stainless steel interface, safely managing continuous wave power loads up to 280 Watts (CW) while completely preserving structural rigidity and excellent boresight accuracy under continuous industrial duty cycles.
