Abstract
A method and a device in a homodyne receiver including a local oscillator generating an oscillator signal at a frequency of f.sub.LO, a mixer, and a reception device for receiving an input signal having a frequency of f.sub.RF, the oscillator signal and the input signal being supplied to the mixer. The oscillator signal is supplied to a first processing unit to produce a first output signal having a frequency of M*f.sub.LO, where M is an integer value. The first output signal is supplied to a second processing unit to produce a second output signal having a frequency of M*f.sub.LO /N=f.sub.LO, where N is an integer number and M.noteq.N, and the mixer and the second processing unit are integrated to minimize leakage of signals being supplied to the mixer from the second processing unit.
