Crossguide Directional Waveguide Couplers

Crossguide Directional Waveguide Couplers

Narda-MITEQ manufactures crossguide directional couplers covering a wide frequency range in either brass or aluminum. 

Narda-MITEQ's single arm cross guide couplers are available with multiple flange and coaxial connector types and configurations to cover all requirements you may have for microwave couplers. Dual arm cross guide directional couplers are also available.

Models are available with 2, 3 or 4 waveguide ports and SMA, Type-K and Type-N connectors. These crossguide directional couplers cover full waveguide frequency and have standard coupling of 30db, 40db or 50db, however other values are available upon request.

Pressure sealed cross guide 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.

TYPICAL SPECIFICATIONS
CROSSGUIDE & DIRECTIONAL COUPLERS

• Full waveguide frequency range
• Single Arm standard, Multiarm model available
• Available in Aluminum or Copper/Brass
• Narda-MITEQ's 300 series typically handles the full guide rating.  All other series typically handle the guide rating in the forward direction.
• Coupling: 30, 40, or 50dB (other values available consult factory for details)
• Internal termination rated at 2 watts.  In the reverse direction or when used as an injector the internal termination shouldn't see more than 2 watts CW
