GENERAL SPECIFICATIONS Impedance: 50 Ω nom. SMA Connectors: Female, to meet the interface rqts of MIL-C-39012 Operating Temp: -- 55° to +85°C Other connectors: TNC and N type available General Notes: 1. The CSM series directional couplers are miniature three port devices utilizing stripline technology in a connectorized package. Each is a quarter wave coupler operating across an octave band of frequencies. They are ideally suited to monitor forward or reflected power with minimal perturbation to the main line signal, signal sampling, control loops and for test signal injection devices in BITE. 2. These devices comply with MIL-C-15370 and may be supplied screened for compliance with additional specifications you designate for military and aerospace applications requiring the highest reliability. 20Mar96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
