General Notes: 1. Units in the CDM series of dual directional couplers comprise two directional couplers back-to-ba ck designed to monitor both forward and reflected power with minimal perturbation to the main line signal. 2. Each miniature coupler is a multi section quarter wave coupler utilizing stripline technology des igned to cover an octave band of frequencies. 3. Dual directional couplers with unequal coupling values or dual in-line configuration may be custo m ordered with coupling values up to 30 dB and with coverage extending over selected frequency bands up to 18 GHz. 4. Merrimac directional couplers comply with MIL-C-15370 and may be supplied screened for compliance with additional specifications you designate for military and aerospace applications requiring higher rel iability Package Outline NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 3. Weights are nominal on all outlines. 21Feb96
