  • Abstract
    Several authors have shown that a great deal may be learned about the operation of a crystal mixer merely by examining its dc voltage-current curve. This curve can yield such useful information as the optimum rf source resistance, minimum conversion loss, optimum mismatch, and the IF output resistance. In addition, if the crystal noise temperature ratio is measured, one can also supply information concerning the optimum intermediate frequency and minimum mixer - IF amplifier noise figure.
