General Notes:
1. Bi-directional couplers in the CRZ-B
CaseFree
series are size and process
compatible with MMIC and other similar
sub-miniature components. Their low
0.130" profile facilitates integration with
hermetic packages using silver epoxy,
solder or wire bonding attachment
methods.
2. Similarly constructed couplers are
available in the CBZ-B series with the
"reverse coupled port" terminated for
use as a 3-port directional coupler.
3. Applications of directional couplers
include monitoring of incident and
reflected power, signal sampling for
control loops and test signal injection
devices in BITE.
