ABSTRACT:
A mixer circuit in which a high frequency signal and a local oscillation signal are applied to two ports respectively of a rat-race having four ports, and the other two ports are connected at one end thereof to grounded diodes respectively. An intermediate frequency signal is derived from a filter connected to a circular loop in the rat-race. The distances of the two arcuate transmission paths between the connection point of the filter and the diodes are selected to be equal to each other, and the two arcuate transmission paths between the connection point of the filter and the high frequency signal input port are selected to have a distance difference corresponding to one half the wavelength of the high frequency signal.
