MEASURING AND MINIMIZING DIODE DETECTOR NONLINEARITY

The paper describes a technique for measuring the linearity of amplitude detectors in general, and for measuring the deviation from square-law, E, of point-contact diode detectors in particular. A general mathematical model is given for determining the rf input power as a function of the detector output voltage. For point-contact diodes it is shown how to choose the video load resistance to minimize E, as well as how to calculate and correct for E.
