Title: Innovations by Sibei Xiong: Pioneering Advances in Bandpass Filter Technology

Introduction

Sibei Xiong, an inventive mind located in Tsukuba, Japan, has made significant contributions to the field of electronic components through his innovative work. With a patented invention focusing on bandpass filter technology, Xiong showcases the intersection of creativity and engineering.

Latest Patents

Xiong holds a patent for a “Bandpass Filter and Process of Fabricating the Same.” This advanced bandpass filter integrates a combination of a bulk acoustic wave (BAW) filter and a patterned planar filter with stubs. The BAW filter is designed using multiple piezoelectric resonators to achieve a specified frequency bandpass, while the planar filter effectively attenuates frequencies that are near and beyond the bandpass range. Notably, the resonators are arranged in a ladder configuration, bridging a first signal transmission path and ground, while the planar filter constructs a strip line on a dielectric layer, establishing a second signal transmission path. By merging both filters on a common substrate, the innovation enhances deep near-band rejection inherent to BAW filters, delivering excellent out-of-band rejection across adjacent frequency ranges, hence achieving a sharp and wide bandpass.
