Description & Specification
WC-42-PBR-KF Waveguide to Coaxial Adapter
K-Band Precision Transition | 2.92mm K-Female Interface | 18 - 26.5 GHz
The WC-42-PBR-KF is a high-performance Waveguide to Coaxial Adapter professionally engineered for precision K-Band transitions within the 18 GHz to 26.5 GHz spectrum. Optimized for professional Signal Security and mission-critical Signal Defense infrastructures, this component features a robust continuous power handling capacity up to 280 Watts (CW). Integrating a standardized UG-595/U (UBR 220) waveguide flange and a high-durability stainless steel K-Female connector interface, it ensures low-loss coupling and pure Signal Integrity with an optimized maximum VSWR of 1.25 : 1. Fully machined from aerospace-grade aluminum in Taiwan, it serves as the primary choice for unwavering stability in high-frequency microwave links, tactical deployments, and millimeter-wave laboratory setups.
