Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 3. Weights are nominal on all outlines. General Notes: 1. The CTM series directional couplers are miniature three port devices utilizing stripline technology in a connectorized package. Each is a multi-section quarter wave coupler designed to cover a broad bandwidth. They are ideally suited to monitor forward or reflected power with minimal perturbation to the main line signal, signal sampling, control loops and test signal injection devices in BITE. 2. A variety of models may be custom ordered with coupling values up to 30 dB and covering frequency bands up to 18 GHz. 3. These units comply with MIL-C-15370 and may be supplied screened for compliance with additional specifications you designate for military and space applications requiring the highest reliability. 16Aug99 F rf t e if r to c n a tM ERRI AC /41 Faifel Pl,W estCal el,NJ,07006 / 973-575o ur h r n o ma in o t c M ri d . dw l 1300 /FAX 973- 0531 575-
