The switching device has an RF switch, with which a signal route formed respectively in the RF switch, is embodied asymmetrically, in that the signal route in a reception circuit configuration and the signal route in a transmission circuit configuration have a different number of switching stages. A FMCW radar transceiver, and a method for the operation of a front end are also disclosed.
