Directional Couplers

Cobham Signal & Control Solutions - Directional Couplers

Cobham Signal & Control Solutions' miniature stripline couplers, series CA, are available in these coupling values:

  • 6dB
  • 10dB
  • 20dB
  • 30dB

These units feature high directivity and low VSWR and are concervatively rated to ensure the most reliable service and performance.

The directional couplers on this page are unequalled in terms of size and performance. The volume of these couplers make them ideally suited for applications involving high density packaging.
