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.
