Abstract
A first and a second signal (base band and local oscillator), respectively modulated to a first and a second frequency, are mixed to deliver an output signal at a frequency obtained by combining the first and second frequencies. The mixing is accomplished through a variable resistance stage controlled by the second signal and connected between a first and a second potential to deliver the mixed output signal. A control stage is configured to drive the resistance variation of the variable resistance stage according to the first signal.
