Dolph Microwave manufactures Waveguide Directional Couplers covering a wide frequency range from WR2300 to WR10. Couplers are available in 3 or 4 port configuration. Standard coupling values are 20, 30,40, 50 and 60 dB, with minimum Directivity of 18 dB. The compactness of waveguide coupler suits many applications where space is at a premium and directivity is not the prime consideration. Models are available with combinations of waveguide and coaxial ports. Special multi-port waveguide couplers can be manufactured to suit customer's special requirements. Following is taking crossguide type 2 Waveguide Ports, 1 Coax Port as example.
Note: Broadwall type and loop type are both optional

Flange type: Multiple types available - see Dolph Microwave Flanges page.
Finish: Corrosion protection plus black top coat.
