Description & Specification
WC-034-UBR-KF Waveguide to Coaxial Adapter
Ka-Band Precision Solution | 2.92mm K-Female Interface | 22.0 – 33.0 GHz
The WC-034-UBR-KF is a high-precision Waveguide to Coaxial Adapter professionally engineered for the WR-34 standard. Operating within the 22.0 GHz to 33.0 GHz spectrum (Ka-Band), this precision component ensures an ultra-low-loss transition for superior Signal Integrity. Featuring a high-durability Stainless Steel K-Female (2.92mm) connector and a standardized UG-1530/U (UBR) flange configuration, it reliably handles massive continuous power loads up to 250 Watts (CW) with an optimized maximum VSWR of 1.25 : 1. Fully machined from high-grade aluminum in Taiwan, it serves as the primary choice for 5G millimeter-wave communications, high-frequency radar sub-systems, and advanced laboratory measurement infrastructures.
