SIGNAL SPLITTING NETWORK WHEREIN AN OUTPUT FROM SECOND COUPLER IS FED BACK TO ISOLATED PART OF FIRST COUPLER

摘要

A composite coupler is disclosed formed by a pair of analogous quadrature couplers. Energy passed from the first coupler to the second is fed back to the first initiating a recirculating effect which provides composite coupling characteristics described by a higher order differential equation than describes the original pair of couplers.
