The Cernex CDC series of multi-hole directional couplers is available for the frequency range 18 to 110 GHz in seven waveguide bands.
The standard coupling levels are 3, 6, 10, 30 and 40 dB with full waveguide operational bandwidth. The couplers are rugged and feature high directivity which is achieved via a low VSWR built-in termination.
The couplers are typically used for power sampling or frequency monitoring with minimum signal loss (0.7 dB up to 50 GHz) on the main transmitting path.
