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. Units in the CDM series of dual directional couplers comprise two directional couplers back-to-back 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 designed to cover an octave band of frequencies. 3. Dual directional couplers with unequal coupling values or dual in-line configuration may be custom 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 reliability 21Feb96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 |
