Then: Similarity Considerations for Varactor Multipliers

INTRODUCTION

This paper is concerned with the connection between the varactor equivalent circuit and harmonic generator performance. Substantial progress has recently been made in the detailed analysis of multiplier circuits by several workers; these results will likely be published in the near future. Instead of borrowing from these new results, the present paper will show the extent to which the problem can be surrounded by general arguments based mainly on dimensional analysis.

In fact, the combination of a few early experimental results with dimensional analysis provides a basis for preliminary multiplier design _ particularly the initial selections of varactor diodes.

The discussion can and will be carried out without any circuit diagrams. But it will be apparent that important existence assumptions about circuits are involved. It is implicitly assumed, for example, that at least one optimum multiplier circuit exists for a given order of multiplication.
