W62SF-U140R - WR-62 Waveguide to SMA Female Adapter – Ku-Band 11.9–18 GHz

WR-62 to SMA Female Adapter for Professional Ku-Band Applications

This WR-62 waveguide to SMA female coaxial adapter is designed to provide a stable, precise and low-loss transition across the 11.9–18 GHz range, covering the entire Ku-Band. It is a professional QAXIAL solution ideal for advanced RF systems, microwave telecommunications, radar modules and laboratory measurement setups.

The SMA female interface is the most widely used industrial standard for applications up to 26.5 GHz, offering an excellent balance of RF performance, mechanical robustness and cost efficiency. The UBR-140 square flange ensures full mechanical compatibility with WR-62 waveguide interfaces, while the internal geometry is optimized to minimize insertion loss and maintain a low VSWR across the operating band.

Reliable RF Performance in Ku-Band

In the 12–18 GHz range, machining accuracy, internal alignment and connector stability are essential to achieving repeatable performance. Each QAXIAL WR-62 to SMA female adapter is manufactured using high-precision machining and strict dimensional controls to ensure a stable and reliable waveguide–coaxial transition in demanding professional and industrial applications.

These characteristics make this adapter an excellent choice for professional RF systems, Ku-Band telecom equipment, radar front-ends and test configurations up to 18 GHz.
