ABSTRACT:
A mixer circuit formed of a micro strip line for converting an input signal in SHF band into an intermediate frequency signal in UHF band is disclosed which includes an arch-shaped half-wavelength line having a length equal to one half of the wavelength of the input signal and a series circuit of two diodes connected between both ends of the half-wavelength line, and in which the input signal and a local oscillation signal are applied respectively to the junction point of the diodes and one end of the half-wavelength line, and the intermediate frequency signal is delivered from a given point on the half-wavelength line.
