Mixer

A device in which two or more input signals are combined to give a single output signal. In satellite communication systems, it is a non-linear device used to generate a replica of an input signal at a higher or lower frequency by multiplying the input signal by a pure tone of a different frequency (the "local oscillator" signal). Usually part of a frequency conversion process. For example, an LNB local oscillator signal at 10.6 GHz mixed with incoming signal at 12 GHz would convert the input signal to an IF frequency of 12 -10.6 = 1.4 GHz.
