Title: The Innovations of Renhu Luo: A Pioneer in Cross-Coupled Filter Technology

Introduction

Renhu Luo is an accomplished inventor based in Suzhou, China. With a strong focus on innovative technologies, he holds a total of two patents that contribute to advancements in the field of resonant structures. His inventions, particularly in cross-coupled filters, showcase a blend of structural miniaturization and enhanced electrical performance.

Latest Patents

Renhu Luo’s latest patents, both centered around cross-coupled filters, highlight his inventive prowess. The first patent describes a cross-coupled filter featuring a minimum resonant structure composed of four resonators. In this design, resonators within the same row are capacitively or inductively coupled, while those in the same column are hybrid coupled both electrically and magnetically. This arrangement allows for opposite coupling polarities between the two groups in adjacent rows, facilitating cross-coupling. The innovation emphasizes structural miniaturization and lightweight characteristics and achieves low loss alongside excellent harmonic performance.

The second patent expands on the concept of a cross-coupled filter with a resonant structure comprising multiple columns of resonant units, where each column contains at least two resonators. This design alternates the dominant coupling modes of adjacent resonators between electrical and magnetic coupling, again establishing cross-coupling among the resonators in adjacent columns. Such unique configurations further realize low loss and improve harmonic characteristics, further enhancing the utility of the technology.
