MESFET倍频器的最佳设计

Optimal Design of MESFET Frequency Multipliers

本文提出一种适用于优化倍频器终端，具有最大输出功率（Ｐ＿ｏｕｔ）和变换增益（Ｇ＿ｃ）的设计准则。这种设计技术，首先是在线性Ｓ参数基础上，推导出ＭＥＳＦＥＴ终端的计算。尽管相当简单，但这种近似法导出了期望的结果。使用该方法，获得了曾经报导过的最大输出功率变换增益的折衷法，实验与模拟结果相当吻合。

Abstract：In this paper，a design criterium for optimizing frequency doubler terminationsfor maximum output power（P_out）and conversion gain（Gc）is proposed The design technique，based at a first step on linear S parameters，lead to the calculation of the MESFET termina-tions．Although rather simple，this approximation led to promising results：with this method，the highest output power-conversion gain trade-off ever reported was achieved and，also，the experimental and simulation results agreed closely.
