Waveguide Couplers,

Broadwall Multi-hole Directional, Dual

ATM Waveguide Dual-arm multi-hole directional couplers are similar to our regular Broadwall Multi-hole Directional Couplers, only with the addition of a second coupling output. Full frequency ranges are covered, and multiple flange and coaxial connector types are available. For more information feel free to call us and discuss your needs with one of our design engineers.
