General Notes:

1. The CWM-R series of directional couplers consists of 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.

2. Similar directional couplers may be custom ordered with coupling values up to 35 dB and covering frequency bands up to 26.5 GHz.

3. These units 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.
