Exploratory Research and Development of Microwave Filters in Silicon Technology

Abstract

The objective of the project is to explore topologies and techniques to realize microwave filters in a standard silicon process. A wideband differential-mode combline filter with a tapped-line input is presented. High suppression of the common-mode and a small size are two important features of the proposed filter. The filter combines two conventional combline filter connected together through discrete capacitors. The realised sixth-order balanced combline filter has a 3 dB bandwidth of 74% from 0.88 to 1.9 GHz. The common-mode suppression is larger than 29 dB, even up to 5 GHz. Furthermore, the filter core size (0.026 lambda(2)(g)) is substantially smaller than previously reported wideband balanced filters.
