Open publisher page 2 citations

Abstract

A Miniaturized wide stopband quasi-ellipse filter is presented using Si-based IPD technology. To demonstrate the working mechanism of the proposed BPF, an LC circuit is conceived and analyzed for further study of transmission zeros and poles. The proposed BPF is implemented in the Si-based IPD technology and simulated. A transmission zero is generated above the center frequency due to the cross-coupling, which improves selectivity and out-of-band suppression. It has a center frequency of 2.95GHz with a 3-dB bandwidth of 20.3%, and a minimum insertion loss of 2.08-dB within the passband. The stopband suppression from 3.8GHz to 11GHz is greater than 30-dB. The chip, including the GSG pads, is about 2.33mm×2.36mm.
