Latest Patents
Qiang Li's latest patents focus on the development of cross-coupled filters. One of his inventions describes a cross-coupled filter that includes a minimum resonant structure comprising four resonators. In this structure, two resonators in the same row form a group, and they are capacitively or inductively coupled. Additionally, two resonators in the same column are electrically and magnetically hybrid coupled. The coupling polarities of the two groups of resonators in the two rows are opposite, creating at least a cross-coupling. This invention achieves miniaturization and lightweight characteristics while ensuring low loss and excellent harmonic performance.
Another patent by Qiang Li also details a cross-coupled filter with a resonant structure that includes multiple columns of resonant units. Each column consists of at least two resonators, with dominant coupling modes alternating between electrical and magnetic coupling. This design further enhances miniaturization and light weight, while maintaining low loss and good harmonic characteristics in electrical performance.
