摘要

提出了一种求出给定MESFET最佳工作条件的方法,以获得最优倍频器。该方法的关键在于不需要先验地选择嵌入网络的拓扑结构。找到了最佳偏置电压和最佳负载阻抗(包括可能的反馈电路)。该方法已应用于设计10- 20ghz低频和20- 40ghz毫米波频率的倍频器。虽然实验倍率仍在测量中,但初步结果与理论预测很好地吻合。

Optimal CAD MESFETs frequency multipliers with and without feedback
A method is proposed for deriving the optimal operating conditions of a given MESFET needed to obtain an optimal frequency multiplier. The key point of this approach is that no topology of the embedding network is to be chosen a priori. The optimum bias voltages and the optimum load impedances (including possible feedback circuit) are found. The method has been applied to design doublers at low frequencies from 10-20 GHz and at millimeter-wave frequencies from 20-40 GHz. Although the experimental doublers are still under measurement, first results have given good agreement with theoretical predictions.<>
