摘要

根据微带线的色散特性和耦合传输线的原理，提出了一种工作在传输模式下，可用于模拟信号处理的色散延迟线。本文从理论和实验两方面证实了通过调整微带结构中级联c段的长度可以获得期望的群延迟响应。利用CST Microwave Studio电磁仿真软件对优化后的结构进行了仿真，在0.2 GHz ~ 3.85 GHz范围内获得了满意的啁啾群延迟。实验原型是集成在微带基板上的共面设计，上面有屏蔽铝盖。通过样机试验和时域分析验证了级联c截面的色散特性。

Research of chirped dispersive delay line based on the dispersion characteristics of microstrip lines

Based on the dispersion characteristics of microstrip lines and theory of the coupled transmission line, this paper presents a dispersive delay line which works in the transmission mode and could be used in analog signal processing. This paper theoretically and experimentally confirms that desired group delay responses could be achieved by tuning the lengths of cascaded C-sections in the microstrip structure. The optimized structure is simulated by the electromagnetic simulation software CST Microwave Studio, and a satisfied chirped group-delay is achieved ranging from 0.2 GHz to 3.85 GHz. The experimental prototype is a coplanar design integrated on a microstrip substrate with a shielded aluminum lid above it. The dispersion of the cascaded C-sections has been verified by prototype test and its time-domain analysis.
