STRIP TRANSMISSION LINE BROADBAND 4:1 IMPEDANCE TRANSFORMER

摘要

An electrical transformer for transforming electrical impedances in a four-to-one ratio includes a dielectric substrate having U-shaped metallized conductors deposited on opposite surfaces of the substrate, the two U-shaped conductors being substantially superimposed on each other, and having one end of one of the conductors connected to the nearest end of the other conductor through a hole in the substrate. The transformer provides a four-to-one impedance transformation between an input port including the first and second ends of one of the U-shaped strips and another port including the unconnected ends of the two strips.
