Six-port precision directional coupler

A design for a six-port, high phase and amplitude balance, stripline coupler is presented. Both the predicted and the measured performance of a hardware prototype show phase and amplitude balance better than 0.2 dB and 0.9 at the design frequency of 2.46 GHz when fabricated on an FR-4 substrate.
