The most important thing we build is trust
DESCRIPTION:
Cobham Signal & Control Solutions’ 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 makes them ideally
suited for applications involving high density packaging.
