FT-RF WR90 Waveguide Adapter
FT-RF WR90 Waveguide Adapter is a precision-engineered X-Band waveguide-to-coaxial adapter (8.2 GHz to 12.4 GHz) designed to seamlessly connect WR90 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 defense radar cross-section (RCS) testing, anechoic chamber calibration, 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.
