Double Ridge Waveguide Couplers
Overview
Looking for a double ridge waveguide coupler? You’ve reached the right place. No matter what your design need, Frontgrade has a solution to meet all of your design needs.
Designed with decades of waveguide expertise, Frontgrade Double Ridge Waveguide Couplers provide field proven performance and reliability.
Frontgrade 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
Frontgrade 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.

Cross Guide
Coax Secondary Broadwall Directional Couplers
Frontgrade Coax Secondary Broadwall Couplers covering the double ridge waveguide sizes WRD-180 through WRD-250. The optimum waveguide characteristics of high directivity and coupling flatness are achieved utilizing a precision machined Tchebyscheff coupling hole distribution and a precision ground tapered load element in the secondary arm.
