The invention is directed to a frequency conversion circuit arrangement a
mobile radio containing such circuit which provide frequency conditioning
with a frequency mixer. In this context, a feedback path from the output
of the frequency mixer to a further input on the frequency mixer is
provided which has a frequency divider. Particularly if the frequency
divider is in the form of a divide-by-two frequency divider, the
frequency conversion circuit exhibits low power and has a small chip area
and permits the circuit to be operated without reaction on a frequency
generator in order to actuate a frequency converter for a useful signal
in a transceiver.
