U-Band Block Type Directional Couplers

Our U-band Block Type Directional Couplers are for the spectrum in the millimeter wave range of frequencies from 40 to 60 gigahertz (GHz).

The 561 Series Directional Couplers provide an efficient and convenient means for sampling a finite quantity of power flowing in a transmission line or for injecting a desired signal into the line.

Note: Our website contains just a few of the type of couplers we build. Consult with us for your specific needs.
