The range from the minimum, which is at a level at or below the amplifiers' internally-generated noise, to a maximum input signal level that a component can accept and amplify without distortion. In regard to mixers, the range of RF input power levels over which a mixer can operate within a specified range of performance. The upper limit of the mixer dynamic range is controlled by the conversion compression point (also a function of LO drive), and the lower limit is set by the mixer noise figure.
