Balun device for UHF signals

摘要

A balun device for UHF signals includes two conductive connection pads, a printed conductive track and a conductive ground pattern that are formed on a dielectric base plate. The conductive connection pads are connectable respectively with a pair of first signal lines for a pair of differential signals. One of the conductive connection pads is further connectable with a second signal line for a single-ended signal. The printed conductive track interconnects electrically the conductive connection pads. The conductive ground pattern is surrounded by and spaced apart from the printed conductive track and the conductive connection pads.
