face requirements
of MIL-C-39012.
General Notes:
1. The CGN-30-G series of high power dual directional
couplers monitor both forward and reflected power on
antenna feeds. They comprise directional couplers on
each side of the main line to minimize coupled length
and resulting insertion loss. Models are available for
Cellular, GSM and PCN/PCS base stations.
2. Heat generated by losses and reflections is quickly
dissipated from the main line through highly
conductive materials and loads to optimize
performance and enhance reliability.
3. These models comply with MIL-C-15370 and may
be supplied screened for compliance with additional
specifications you designate for military and aerospace
applications requiring higher reliability.
