Overview

Looking for a double ridge waveguide coupler? You’ve reached the right place. No matter what your design need, CAES has a solution to meet all of your design needs.

Designed with decades of waveguide expertise, CAES Double Ridge Waveguide Couplers provide field proven performance and reliability. 

CAES provides an extensive portfolio of double ridge waveguide couplers. Our portfolio includes a full range of cross guide directional, broadwall and dual-arm broadwall directional couplers.

Cross Guide Couplers

CAES Cross Guide Couplers utilize an ultra-flat coupling technique that exhibits high power handling characteristics while maintaining optimum electrical parameters over octave waveguide bandwidths. Included in the design characteristics are rugged dip-brazed construction, minimum directivity of 15 dB, maximum VSWR of 1.20, and coupling levels available ranging from 35 to 60 dB with a mean variation less than ±1.0 dB.
