... Package Outline 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 ...
