Description & Specification
K-Band WR-42 Waveguide to Coaxial Adapter
UG-595/U Flange to SMA-Female | 18.0 GHz - 26.5 GHz
This precision-engineered WR-42 Waveguide Adapter provides a seamless, high-fidelity transition between millimetric waveguide systems and coaxial components in the K-Band spectrum. Operating across the full 18.0 GHz to 26.5 GHz frequency range, it features a standardized UG-595/U flange and a high-performance SMA-Female connector. Constructed from aerospace-grade aluminum with a stainless steel interface, this adapter ensures maximum Signal Integrity, low V.S.W.R (1.25), and robust power handling up to 280 Watts for both laboratory and field-based RF sub-systems.
