SUB-MINIATURE
COUPLERS, DIRECTIONAL SERIES CA, CL
SMA FEMALE 0.5-18 GHz
GENERAL INFORMATION
KDI/Triangle miniature stripline couplers, are available in 6 dB, 10 dB,
20 dB and 30dB, coupling values. These units feature high directivity
and low VSWR and are conservatively rated to ensure the most reli-
able service and performance under severe environmental conditions.
The directional couplers shown 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. As evi-
denced by the specifications, no compromise has been made with
electrical performance in order to achieve sub-miniaturization.
