COUPLERS, DIRECTIONAL SERIES CA-N
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.
GENERAL SPECIFICATIONS
Frequency Range: 0.5 to 3 GHz
RF Impedance: 50 Ohms
RF Power: 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.
Operating Temperature: 55C to +85C
Connectors: N Female
Notes:
1. Rugged 4 hole connector construction insures mechanical superiority.
2. A 50 ohm termination is supplied on each unit delivered. Power rating
is 1.0 watts at +25C
