| 摘 要： | 从PIN二极管基区双极载流子扩散方程出发，通过拉普拉斯变换求解得到PIN二极管子电路模型，从而通过PSpice软件瞬态数值模拟得到了PIN限幅器的尖峰泄漏、平顶泄漏与脉冲功率、上升时间关系。对于I层厚度一定的限幅器，模拟与实验表明脉冲前沿越大，尖峰泄漏功率插入损耗越大，脉冲前沿过缓则可能没有尖峰泄漏现象；尖峰泄漏功率随着输入功率的增加而变大，但尖峰泄漏功率插损也随之增大；尖峰脉冲宽度与I层厚度、输入功率及脉冲前沿均有关系。限幅器尖峰泄漏与平顶泄漏模拟结果与实验数据基本一致。

| Abstract: | A time-domain model of PIN diode limiter has been studied with PSpice code in this paper. The Q-I relationship of the l-region is obtained using the Laplace transform and Pad6 approximation based on the base area ambipolar carrier transport equation. The proposed limiter circuit model takes into account the input RF power, the pulse rising time and the width of the Iregion. Simulation results and experimental studies show that PIN diode limiter spike leakage characters are determined on the microwave pulse power and rising time. It is a transient effect and might not be observed with a slow rising time pulse. |
