PREFERRED-CIRCUIT TECHNIQUES FOR CRYSTAL-DIODE MIXERS.
Abstract
This report describes an investigation of circuit techniques to minimize spurious responses in crystal-diode mixers. Equations are presented for a single-diode mixer, balanced mixer, double-balanced mixer, and image-rejection mixer. Measurements are presented for the performance of these mixer configurations as a function of DC bias current. These measurements are used to compare: (1) the experimental results with the theoretical predictions of the effects of bias current and (2) the performance of the various circuit configurations. In addition, a 10 x 10 matrix of diodes and a 12 x 12 microelectronic matrix of diodes were constructed and used to substitute as a single diode in mixer circuits. It was shown analytically and experimentally, that such an array when compared with a single diode can be used to increase the dynamic range and reduce certain spurious responses. (Author)
