Peak Power, Main Line: 10 kW peak max. Impedance: 50 Ω nom. Operating Range: -- 55° to +85°C Connectors, SMA/N-type: To meet the interface 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. 24May96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 CGN-30-G Series DUAL DIRECTIONAL COUPLERS 0.7 to 8 GHz / Very Low Insertion Loss / 500 W CW Failsafe / 30 dB Coupling to Both Ports / Ntype B - Package Outline NOTES: 1.
