KU & X BAND (8.20 GHz – 18.00 GHz)
Ku-Band & X-Band Waveguide to Coaxial Adapters
High-efficiency Ku-Band & X-Band Waveguide to Coaxial Adapters covering 8.20 GHz to 18.00 GHz (WR62, WR75, and WR90). Fitted with N-Type and SMA precision connectors, these adapters guarantee low VSWR and excellent return loss for defense and SatCom test setups.
Essential interconnects for airborne radar feeds, marine surveillance systems, satellite ground links, and VNA test benches.
*Custom UG, UBR, CPR, and FDP flange configurations available upon request.
⚡ Core Engineering Highlights
8.20 – 18.00 GHz Span
Full-band coverage for WR62, WR75, and WR90 waveguides.
Low Insertion Loss
