Modifying branch-line coupler design to enhance six-port reflectometer performance

Hybrid couplers are commonly utilized as the building blocks of six-port reflectometers but unfortunately the resulting instruments do not comply with the optimum design specifications. A previous attempt to rectify this defect employs modified rat-race couplers which are not easy to inter-connect d...
