Directional Broadwall Multi Hole

Broadwall Multi-hole Directional Couplers

Narda-MITEQ manufactures Waveguide multi-hole directional couplers in a variety of configurations, covering a full frequency range with multiple flange and coaxial connector types.

This single arm broadwall directional coupler covers the full waveguide frequency and is available in either aluminum or copper/brass construction. Dual arm broadwall multi-hole directional couplers are also available.

Models are available with standard coupling values of 3dB, 6dB, 10dB, 20dB, 30dB, 40dB, or 50dB. Pressure sealed broadwall multi-hole directional couplers are also available for microwave applications that require sealed systems.

For more information feel free to call us and discuss your needs with one of our design engineers.
