MICROWAVE & MILLIMETER-WAVE COMPONENTS
Waveguide to Coax Adapters (WC)
The FT-RF Waveguide to Coax Adapters (WC Series) deliver high-efficiency conversion between rectangular waveguide propagation modes and standard 50 Ω coaxial transmission lines. Featuring precision-engineered N-type and SMA connectors, this series spans frequencies from 320 MHz up to 40 GHz while maintaining superior low VSWR performance and minimal insertion loss.
These adapters serve as vital interconnect solutions for bridging microwave waveguide systems with coaxial RF instrumentation, attenuators, switches, and couplers. They are widely deployed across satellite ground station terminals, terrestrial microwave links, and high-precision laboratory test benches.
*Custom waveguide flange options (UG/UBR/FBP), right-angle/end-launch configurations, and high-frequency millimeter-wave adapters available upon request.
⚡ Next-Gen Engineering Highlights
