摘要

A complete design method is presented for the Grounded Grid crystal oscillator, operating in the frequency range of 75 to 150 mc. Design information is presented in the form of graphs and tables. A reference circuit, having a single set of values for the frequence range covered has been devised, and by varying the circuit component values measurements of performance have been made and plotted. The resulting graphs are normalized with respect to the reference circuit component and performance figures. In this way, output and crystal drive voltage variations were determined for specific changes in circuit parameters. The accuracy of performance prediction is 20 to 25 percent for output voltage and 35 to 40 percent for crystal drive voltage.
