Frequency Multiplier Analysis and Design Using Punch-Through Varactor Diodes

摘要

Punch-through varactor diode frequency multipliers, a type of nonlinear reactivemultiplier, can be 100% efficient, theoretically. This report presents a model of a punch-through diode and then analyzes it in the frequency domain. By restricting the currents that can flow, the analysis can be reduced to a finite set of equations for any order multiplier. Next, assuming that the diode loss is low enough, diode equations for the specific cases of a doubler and a tripler are developed. The report then adds the necessary circuit elements to give lumped-element circuit designs and design equations for both doublers and triplers. Finally, sample circuits are built using these designs, and design equations are shown along with their performance.
