WR-42 to 2.92mm Female K-band Waveguide to Coax Adapter End-Launch
MODEL NUMBER: TRCW-429FEG0 - K-band, WR-42, 18 - 26.5 GHz
The WR-42 Female K-band Waveguide-to-Coax End-launch adapter provides a compact, precision transition from WR-42 (18–26.5 GHz) rectangular waveguide to a high-frequency female coax interface (commonly 2.92 mm). Its end-launch probe is optimized for minimal discontinuity at the waveguide aperture, delivering low VSWR and low insertion loss across W-band. CNC-machined, gold-plated conductors and tight-tolerance alignment features ensure repeatable measurements in mmWave test setups, radar front-ends, 5G/6G research, and imaging systems. Compatible with standard WR-42 flanges (e.g., UG-595/U), it offers robust mechanical stability, broadband performance, and excellent mode purity in a lab-friendly form factor.
