Abstract
A Mixer structure (210) for Doppler radar applications and a Doppler radar sensor (30) having an oscillator input port (LO) for output signals from an electric oscillator (32), having a radio frequency input port (RF) for output signals from receiving means (34), having an output port (IF) for an overall output intermediate signal produced in the mixer structure (210) and having two mixer branches (12a, 12b) each with a diode (18a, 18b). The mixer branches (12a, 12b) are connected to the oscillator input port (LO) and to the radio frequency input port (RF) in such a manner that intermediate signals (IF1, IF2), which are produced in these mixer branches (12a, 12b) and correspond to a Doppler shift between the oscillator signal and the radio frequency signal, are processed to the overall output signal.
