详细信息

 

        Aeroflex Control Components‘‘ 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 concervatively rated to ensure the most reliable service and performance. The direction al couplers 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.
