ABSTRACT:
A frequency converting circuit which requires no balance regulation, is usable in a wide frequency band and is suitable to be incorporated in an integrated circuit. A first input signal is supplied to an input terminal 1 and a phase division circuit 2 to produce two phase divided signals from the first input signal. A second input signal is supplied to an input terminal 4 of a switch signal generating circuit 5 which produces two switch signals from the second input signal. A first one of the two switch signals and the two phase divided signals are supplied to a first switch 3. Switch 3 selectively outputs one of the two phase divided signals responsive to the first one of the two switch signals. Another output of the first switch 3 is a signal obtained by inverting a phase of the one selected output signal of switch 3 by means of the phase invertor/amplifier 6. The inverted switch signal of invertor/amplifier 6 is applied to a switch 7 which selectively outputs one of the output signals of this switch 3 and an inverted signal output from the phase invertor/amplifier 6, responsive to the second one of the two switch signals.
