Aeroflex-KDI ‘s Miniature Stripline Couplers, Series
CA are available in 6dB, 10dB, 20dB, and 30dB
coupling values. 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

1) Rugged 4 hole connector construction
insures superiority
* Note 2
2) For all 30 dB 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.
ORDERING INFORMATION
X in the part number represents the coupling value.
6 = 6dB 1.0dB; 1 = 10dB 1.2dB; 2 = 20 1.2dB dB; 3 = 30dB 1.2dB
Examples: CA-516 = .5-1GHz 6dB Coupler
CA-513 = .5-1 GHz 30dB Coupler
