Abstract

Square law detectors in beat frequency oscillators would produce no harmonics of the beat frequency if the square law were not disturbed by the output impedance. A method is here developed for the determination of the magnitude of this effect, depending on the solution of a differential equation by a method of successive approximation. Expressions are given from which the distortion may be estimated, and the conditions for minimum distortion determined.
It is shown that there is an optimum relation between the load resistance and the grid bias, resulting in a relative maximum voltage output. Keeping this relation satisfied, there is again an optimum value of load resistance, and at the corresponding bias with this resistance the maximum output at fixed plate voltage is obtained. The output is at once limited by grid current and cut-off of the plate current, both of which are just to be avoided.
