ABSTRACT:
A local signal of a predetermined frequency is supplied to an input terminal of a local signal input section. The local signal is applied to a control input terminal of a variable current supply and, in accordance with the local signal, a current is output from a variable current supply and sent to a phase-shifting section. The phase-shifting section includes two resonance circuits each comprised of a capacitor and inductor. The two resonance circuits are connected in parallel with a linear element constituting the local signal input section to output first and second output signals of the same frequency as that of the local signal and whose phases are shifted by a predetermined amount. The respective output signals of the phase-shifting section are output to a next stage through a signal output section comprised of two sets each of a current supply and transistor.
