一、前言微波电路计算机辅助设计程序的关键性能是精确度,只有精度高才能发挥微波CAD巨大作用。当前微波通信、卫星广播、电子对抗、雷达、宇航等各微波装备中主要的电路形式是微带混合集成电路。而在微带电路设计中,要想获得高精度必须解决微带不均匀区的精确计算,还要考虑微带线色散、损耗及盒体影响,否则设计指标将与实际制做的电路特性有较
I. INTRODUCTION The key performance of the computer-aided design of microwave circuits is the accuracy. Only the high precision can play a great role in microwave CAD. Currently, the main circuit forms in microwave equipment such as microwave communication, satellite broadcasting, electronic warfare, radar, and aerospace are microstrip mixed integrated circuits. In the microstrip circuit design, in order to obtain high precision, it is necessary to solve the precise calculation of the microstrip uneven area, but also consider the microstrip line dispersion, loss and impact of the box, or design specifications will be made with the actual circuit characteristics More
