COUPLERS, DIRECTIONAL
TYPE N
0.5-3 GHz
GENERAL INFORMATION
KDI/Triangle Miniature Stripline Couplers, Series CA-N, are available in
10 dB, 20 dB and 30 dB, coupling values. These units feature high direc-
tivity and low VSWR and are conservatively rated to ensure the most reli-
able service and performance under severe environmental conditions.

The peak and average power handling
capability of the couplers apply if the main
line is terminated in a 1.25 maximum
VSWR for the 10 dB couplers, and in a
1.75 maximum VSWR for the 20 and 30
dB couplers.
