Overview
CAES offers a full range of RF Couplers for your designs including directional and hybrid couplers.
CAES' forward and reverse dual directional stripline couplers as well as 90 and 180 degree hybrid couplers, are available in 6 dB, 10 dB, 20 dB and 30 dB coupling values. These units feature high directivity and low VSWR and are conservatively rated to ensure the most reliable service and performance.
Directional
Directional Couplers
CAES provides miniature stripline directional couplers. CAES' CAx Series are available in 6 dB, 10 dB, 20 dB, and 30 dB coupling values. These units feature high directivity and low VSWR and are conservatively rated to ensure the most reliable service and performance. Our directional couplers offer unequalled size and performance. The volume of these couplers makes them ideally suited for applications involving high density packaging.
