QWA Series Waveguide to Coax Adapters

 

Characteristics
  • Low Insertion Loss
  • Full Waveguide Band Operation
  • Frequency Ranges 12.4 to 67 GHz

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 band adapters are available from 18 to 67 GHz in K through V bands. Coaxial connectors include N, SMA, K, 2.4 mm and V as appropriate for the application frequency range, with both male and female types. Exceptionally low insertion loss and low VSWR are the key features of this series of adapters.

Two mechanical configurations for the interfaces of these adapters are offered: Right Angle and End Launch. End Launch or in-line version of the adapters are constructed such that the waveguide port and the coaxial connector are in line with each other. These adapters are very compact and useful where right angle adapters are mechanically not suitable.
