DUAL BAND HIGH FREQUENCY AMPLIFIER USING A COMPOSITE RIGHT/LEFT HANDED TRANSMISSION LINE, PARTICULARLY FOR DESIGNING A MATCHING CIRCUIT PROPER TO A DUAL BAND OPERATION

摘要

PURPOSE: A dual band high frequency amplifier using a composite right/left handed transmission line is provided to achieve gain characteristics and matching characteristics by using composite right/left handed transmission lines having different phase angles.;CONSTITUTION: An amplifying device has an amplifying function, and a matching circuit has an impedance matching reaction of an amplifier. The matching circuit has at least one shunt stub and at least one composite right/left serial transmission line. The composite right/left serial transmission line has plural left transmission lines and plural right transmission lines.;COPYRIGHT KIPO 2011
