一、引言限累弛豫模式已成功地用于本体和外延砷化镓二极管的工作,而且这种工作模式已用大信号计算机模拟作了分析。本文提出一个简单的分析,它适用于振荡器的设计,并能说明限累弛豫模式的基本原理。本文还给出在实验中使用的 X 波段波导窗孔电路中限累弛豫振荡的大信号计算机模拟。强调指出,为得到高的直流到射频转换效率,电路应最佳设计。而且,当二极管中存在掺杂梯度时,效率将会降低。
I. INTRODUCTION The limited-relaxation relaxation mode has been successfully used for the bulk and epitaxial gallium arsenide diodes, and this mode of operation has been analyzed using large-signal computer simulations. This paper presents a simple analysis that applies to the design of oscillators and illustrates the fundamental principle of the DFL relaxation mode. This paper also gives a computer simulation of the large-signal relaxation-relaxation oscillation in the X-band waveguide window circuit used in the experiment. Emphasize that, in order to obtain high DC to RF conversion efficiency, the circuit should be the best design. Moreover, when there is a doping gradient in the diode, the efficiency will be reduced.
