Abstract

In this paper, a method combining the Finite-Difference Time-Domain (FDTD) method and the semiconductor drift-diffusion model (DDM) is presented for analyzing transient electro-thermal characteristics of dual PIN diode microwave limiters. the time domain impulse response signals corresponding to the ports of linear electromagnetic field structures are calculated using the FDTD algorithm. These signals are then coupled with the volt-ampere characteristics as defined by the DDM-based dual-PIN diode model. The transient electro-thermal properties of the dual-PIN diode within the actual microwave limiter circuit are analyzed, with the method's accuracy and efficiency validated through comparison with COMSOL simulation results.

双引脚二极管限幅器的瞬态多物理场电路及电热耦合

本文提出了一种结合时域有限差分法（FDTD）和半导体漂移扩散模型（DDM）分析双PIN二极管微波限制器瞬态电热特性的方法。利用时域有限差分算法计算了线性电磁场结构端口对应的时域脉冲响应信号。然后将这些信号与基于ddm的双pin二极管模型定义的伏安特性耦合在一起。分析了实际微波限幅器电路中双pin二极管的瞬态电热特性，并通过与COMSOL仿真结果的对比验证了该方法的准确性和有效性。
