FT-RF WR42 Waveguide Adapter provides high-efficiency, low insertion loss RF energy transition between WR42 standard rectangular waveguide and coaxial connector interfaces (SMA / 2.92mm K). Engineered for high repeatability across 18.0 to 26.5 GHz in K-Band communication and laboratory test equipment.

Manufactured with precision-machined brass/aluminum bodies and gold-plated center contacts, our WR-42 adapter series delivers low VSWR, robust mechanical stability, and high environmental resistance for SATCOM, radar subsystems, and millimeter-wave instrumentation.
