SUB-MINIATURE
COUPLERS, DIRECTIONAL
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.

The peak and average power handling
capability of the couplers apply if the
main line is terminated in a 1.25 maxi-
mum VSWR for the 6 dB & 10 dB cou-
plers, and in a 1.75 maximum VSWR
for the 20 dB and 30 dB couplers.
–55°C to +85°C

Notes:
1. Rugged 4 hole connector construction insures mechanical superiority
2. For all 30 dB couplers B dimension is 0.55/[14.0]
3. 50 ohm termination is supplied on each unit delivered. Power rating is 1.0 watt at
+25°C.
4. Coupling includes frequency flatness & coupling measurement in reference to
input port.
