Abstract
A direct conversion type of frequency transposition device includes a transconductor block receiving the input signal and a current switching block connected to the output from the device. At least the common mode (I+I) is servocontrolled to static output currents from the frequency transposition device on a current proportional to a reference current (I) and independent of the static output currents from the transconductor block.
