GENERAL INFORMATION
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
applications involving high density packaging.

The Peak and Average power
handling capability of the
couplers apply if the main line is
terminated in a 1.25 max VSWR
for the 6 dB & 10 dB couplers
and a 1.75 max VSWR for the
20 & 30 dB Couplers.
