General Notes:

1. The CRG-B series of bi-directional couplers has both coupled ports

available. Units may be ordered with one coupled port terminated internally

with coupling values up to 30 dB and with coverage over selected frequency

bands up to 2 GHz.

2. These units comply with MIL-C-15370 requirements and can be supplied

screened for compliance with specifications you designate for military and

aerospace applications requiring higher reliability.
