摘要： Disclosed are an impedance matching circuit preventing the occurrence of inter-line interference by making currents at adjacent lines flow in the same direction, and a power amplifier having the same. The impedance matching circuit eliminating interference between signal lines includes: a first transformer including a first input line which forms a first loop by a conductor receiving a signal and a first output line which forms a second loop by a conductor outputting a signal at the inner side of the first loop of the first input line to match the impedance of a path of an input signal; and a second transformer including a second input line which forms a third loop by a conductor receiving a signal and a second output line which forms a fourth loop by a conductor outputting a signal at the inner side of the third loop of the second input line to match impedance, wherein the direction of current in the first input line of the first transformer and the direction of current in the second input line of the second transformer are the opposite so that a portion of the first input line of the first transformer and a portion of the second input line of the second transformer adjacent to the portion of the first input line of the first transformer have the same current direction.
