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.
