ス。[Claims for Utility Model Registration] Consisting of an outer conductor of a coaxial feeder line and an n-stage 1/4 wavelength impedance conversion section forming a part of the inner conductor of the coaxial feeder line, it is a high-power signal of a high frequency circuit. In a 1/4 wavelength transformer that performs impedance conversion for a 1/4 wavelength transformer, a 1/4 wavelength transformer is provided between the n stages of 1/4 wavelength impedance converters and between the impedance converter and the inner conductor, and changes the effective length of the impedance converter to change the center frequency. A 1/4 wavelength transformer comprising a variable 1/4 wavelength member.
