QWA Series Waveguide to Coax Adapters

Product Description

QuinStar Technology’s QWA series waveguide to coax adapters offer an efficient method of transition from rectangular waveguide to a coaxial connector. Full waveguide bands available from 12.4 to 67 GHz.

Coaxial connectors include N, SMA, K, 2.4 mm and V as appropriate for the frequency range and application, with both male and female types. Low insertion loss and low VSWR are the key features of these adapters.
