- Abstract
- In this article, we present a new generic reflectionless filter topology that can be used in designing not only a filter having zero reflection at one port but also a filter having zero reflection at both ports. Detailed mathematical analysis of the presented reflectionless filter topology is provided. The three unique features, which will be described throughout this article, allow us to straightforwardly synthesize a reflectionless filter with ease. Hence, the synthesis procedure does not necessitate using either an optimization technique or a numerical method. This article also presents a rigorous design methodology involving closed-form design formulas for distributed-element filters using the proposed topology. The presented filter topology and design methodology have been verified by designing and fabricating bandpass filters.
