Diode phase-sensitive detectors with load

Abstract

A theoretical investigation of the operation of the simple diode push-pull phase-sensitive detector - with load is carried out. The transfer ratios for the two diodes are found to vary considerably with - the signal. The non-linearity in the output due to these variations is evaluated, and a table is given from which the suitability of a given detector may be judged immediately. Experiments confine quantitatively the theoretical results.
