FT-RF WR42 Waveguide Adapter is a precision-engineered K-Band waveguide-to-coaxial adapter (18.0 GHz to 26.5 GHz) designed to seamlessly connect WR42 waveguide systems with SMA or 2.92mm (K) coaxial cables and instruments. With ultra-low VSWR and minimal insertion loss, it provides accurate signal coupling for radar systems, satellite communications, and high-frequency precision measurements.

Constructed from high-precision CNC machined aluminum alloys, this adapter guarantees high cross-polarization rejection (>30 dB) and smooth gain flatness across the entire frequency band, ensuring reliable and repeatable measurement results in laboratory environments.
