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.
