本文讨论了使用薄膜 IPD 技术和四阶切比雪夫交叉耦合架构在 [3.168, 4.752] GHz 频段合成和实现 UWB 滤波器，该架构允许我们在带外引入两个有限传输零点。为了实现该滤波器，考虑了三种实现方法。第一种方法是现有技术的经典使用，即集总元件。第二个是引入分布式电容器，以降低滤波器对工业过程变化的响应灵敏度。最后，由尺寸问题决定，包括使用电磁耦合来抑制电路中的集总电感器。描述了这三个版本并讨论了结果。
This paper deals with the synthesis and realization of a UWB filter in the [3.168, 4.752] GHz band using a thin film IPD technology and a 4th order Chebyshev cross-coupled architecture that allows us to introduce two finite transmission zeroes out of band. In order to realize this filter, three approaches of realization were considered. The first approach was a classical use of the available technology, i.e. lumped elements. The second was the introduction of distributed capacitors to reduce the filter response sensitivity towards the industrial process variation. The last, dictated by size issues, consisted in using electromagnetic coupling in order to suppress a lumped inductor from the circuit. The three versions are described and results are discussed.
