Abstract
Mixer unit for a radar sensor for motor vehicles, having an I mixer and a Q mixer which are connected in parallel branches between an oscillator port and an RF port with the aid of power splitters. A switch is situated between each of the power splitters and the Q mixer which allows the signal arriving from the power splitter to be selectively decoupled from the Q mixer and switched to a high-frequency ground. A transformation element is provided between the high-frequency ground and the particular node point of the power splitter which transforms the high-frequency ground into an open line at the node point.
