ABSTRACT:
A phase shifter is provided between common emitters of two differential transistor pairs of a mixer circuit. The phase shifter changes the phase of a voltage signal input to one common emitter by 180.degree. and applies it to the other common emitter, and causes a current in accordance with the voltage between the common emitters. As compared with the prior art employing two stages of vertically connected differential transistor pairs, the power supply voltage can be reduced.
