FT-RF WR28 Waveguide Adapter is a precision-engineered Ka-Band waveguide-to-coaxial adapter (26.5 GHz to 40.0 GHz) designed to seamlessly connect WR28 waveguide systems with 2.92mm (K) or SMA coaxial cables and instruments. With ultra-low VSWR and minimal insertion loss, it provides accurate signal coupling for 5G FR2 mmWave research, 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.
