引言微波电路的优化设计也同其它领域的优化技术一样,是随着现代科学技术和生产发展的需要而发展起来的。在60年代以前,微波电路采用波导、同轴线或带线电路,其设计方法多采用经典的综合法,然后用调配螺钉和可调短路进行调配,因而调配的自由度大。到60年代,微波晶体管的出现和微波集成电路的迅速发展,对微波电路的设计提出更严格的要求,由于调整困难,或只允许微小调整,所以,要求精确设计微波集成电路。在国外,60年代末期,有关微波电路的计算机辅助设计问题就已有大量报导,其中 DEMON 就是一个大型优化程序。到80年代除了 DEMON 程序更进一扩充外,COMPACT 系列优化程序的内容更广泛,功能也更
Introduction The optimal design of microwave circuits, like other areas of optimization technology, is developed with the needs of modern science and technology and production development. Before the 1960s, the microwave circuit using waveguide, coaxial or strip circuit, the design method to use more of the classic synthesis method, and then use the adjustment screw and adjustable short circuit deployment, and deployment of large freedom. By the 1960s, the advent of microwave transistors and the rapid development of microwave integrated circuits put more stringent demands on the design of microwave circuits, requiring precise design of microwave integrated circuits due to difficult adjustments or only minor adjustments. Abroad, in the late 1960s, there has been a great deal of computer-aided design of microwave circuits. Among them, DEMON is a large-scale optimization program. In the 80’s, besides the expansion of DEMON program, the content of COMPACT series optimization program is more extensive and its functions are more
