FT-RF WR187 Waveguide Adapter is a precision-engineered C-Band waveguide-to-coaxial adapter (3.95 GHz to 5.85 GHz) designed to seamlessly connect WR187 waveguide systems with SMA or N-Type coaxial cables and instruments. With ultra-low VSWR and minimal insertion loss, it provides accurate signal coupling for C-band satellite transponder testing, microwave backhaul links, and high-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.
