The invention relates to a mixer for generating an analog output signal Xfrom an analog input signal Xusing a mixing signal having a mixing frequency f, the mixer comprising: a scaler being configured to sample the analog input signal Xat a plurality of discrete points in time k with a sampling frequency fto obtain a sampled analog input signal X[k] having a continuous signal value, and to generate the analog output signal Xhaving a continuous signal value by scaling the sampled analog input signal X[k] on the basis of a plurality of scaling coefficients A[k], wherein the scaling coefficients A[k] are a time-discrete representation of the mixing signal.

Mixer and method for generating an output signal from an input signal

A communication apparatus including a first mixer configured to generate an analog output signal (X) from an analog input signal (X) using a first mixing signal, a second mixer configured to generate an analog output signal (Y) from an analog input signal (Y) using a second mixing signal, and a local oscillator configured to provide a reference frequency (f), where the first mixer is configured to derive a first sampling frequency (f) from the f, and where the second mixer is configured to derive a second sampling frequency (f) from the f.
