Abstract

An image rejection mixer of reduced power dissipation includes a signal distributor supplied with local signals having a phase difference to distribute the local signals, a first and a second signal mixer for mixing the distributed local signals and RF signals having a phase difference and outputting respective IF current signals, a phase shifter for shifting in phase the respective mixed IF current signals so as to provide them with a relative phase difference of 90 degrees, and a signal adder for adding the respective phase shifted intermediate frequency current signals. The shifter shifts the phases of the respective IF current signals outputted from the first and the second signal mixers.
