Operating Temp: -- 55° to +85°C SMA Connectors: Female, to meet interface requirements of MIL-C39012 Other connectors: TNC and N type available. Check with factory. Other frequencies: Optional General Notes: 1. The CWM-M-G series of directional couplers are miniature three port devices utilizing stripline technology in a connectorized package. Each unit is a multi-section quarter wave coupler designed to cover a very broad band of frequencies. They are ideally suited for monitoring forward or reflected power in EW and similar wideband systems with minimal perturbation to the main line signal. A variety of performance and frequency coverage options are available. 2. These units comply with MIL-C-15370 and may supplied screened for compliance with additional specifications you designate for military and aerospace applications requiring the highest reliability. 22Feb96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973 .575.1300 / FAX: 973.575.0531 DIRECTIONAL COUPLERS CWM-M-G Series 600 MHz to 18 GHz / Ultra-Broadband / 6, 10, 16, 20 dB Coupling / Low Cost Stripline / 50 W / SMA Package Outline NOTES: 1.
