General Notes:
1. The CBZ-B
CaseFree
series are
compatible with MMIC and other similar
sub-miniature components in size and
process. Their low 0.130" profile allows
integration within hermetic packages
using silver epoxy, solder or wire bonding
attachment techniques.
2. Similarly constructed Couplers are
available in the CRZ-B series, with both
coupled ports unterminated for use as a 4
port Bi-Directional Coupler.
3. Applications of directional couplers
include the monitoring of incident and
reflected power, in signal sampling for
control loops, as well as test signal
injection devices in BITE systems.
