Dual Directional Couplers

Cobham Signal & Control Solutions - Dual Directional Couplers

Cobham Signal & Control Solutions' forward and reverse dual directional stripline couplers, are available in these coupling values:

  • 6dB
  • 10dB
  • 20dB
  • 30dB
  • These units feature high directivity and low VSWR and are conservatively 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.

Notes:

  1. Rugged 4 hole connector construction insures superiority.
  2. For all 30dB couplers "B" dimension is .55 inches.
  3. 50 Ohm termination is supplied on each unit delivered. Power rating is 1 Watt at 25°C.
  4. Coupling includes frequency flatness & coupling measurement in reference to the input port. Coupling is standard on these units.
