TRANSMISSION LINE STRUCTURE FOR TUNABLE CHARACTERISTIC IMPEDANCE AND VARIABLE IMPEDANCE TRANSFORMER THEREBY

摘要

Four-terminal transmission lines present invention comprising a first and second input terminals and first and second output terminal relates to a variable impedance converter using relates to an impedance converter, in particular the characteristic impedance conversion is a possible transmission line structure and this in the furnace, inserting the respective switches in the input and output terminals of the one or more four-terminal transmission line having an arbitrary characteristic impedance, and a combination of the input and output terminals in parallel, wherein the parallel open or short in accordance with the operation of the switch provides a structure as possible is, to open or short-circuit with a four-terminal corresponding one of a combined four-terminal transmission line transmission line characteristics, comprising a step of converting the characteristic impedance of the whole of the parallel-coupled four-terminal transmission line impedance conversion transmission lines .
