Abstract
A multi-layer substrate (500) includes a segmented stripline (602) which is formed of multi-layered segment (514, 522, 516) and is proximately coupled to a second stripline (604) to form a directional coupler. The directional coupler (500) provides similar input and output port impedances while allowing for independent control of the coupling. The overall length of the coupler is held constant while individual lengths of the segments of the segmented stripline (602) and the second stripline (604) are increased and decreased to independently control the coupling while maintaining the similar port impedances.
