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.
