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
