Introduction

Qunqiang Hu is an inventor associated with South China University of Technology in Guangzhou, China. His patent work addresses control of intelligent reflecting surface arrays, a technology designed to manage communication channels.

Latest Patents

Hu is named on 1 patent: “Device and Method for Controlling Intelligent Reflecting Surface Array.” The invention describes a control voltage module, a voltage amplification module, and a varactor module connected in sequence. The control voltage module generates a precise, low-amplitude analog signal, which the amplification module raises before sending it to the varactor module embedded in an array subunit. Adjusting the varactor’s output capacitance enables independent, continuous control of each subunit. The disclosed approach avoids the need for a digital-to-analog converter chip, aiming to reduce manufacturing costs while maintaining precision in communication channel management.

Career Highlights

Hu’s listed patent reflects work on electronic control systems for intelligent reflecting surfaces. The invention focuses on combining voltage generation and amplification with varactor-based adjustment to control individual array subunits.
