Title: Jiahui Gao: Inventor in Radio-Frequency Circuitry
Introduction
Jiahui Gao is an inventor based in Suzhou, China, associated with Etra Semiconductor (Suzhou) Co., Ltd. Her patent work concerns phase-shifting circuits and radio-frequency microwave systems.
Latest Patents
Gao is credited with 1 patent, titled “Phase-Shifting Circuits and Radio Frequency Microwave Systems.” The invention describes a circuit that splits an input signal into differential signals carried through two channels. Those channels use a differential-circuit architecture to attenuate signals, transform their quadrants, or perform both operations to produce phase shifts. A second node combines the resulting signals into an output whose phase difference from the input can range from 0 to 360 degrees.
Career Highlights
Gao’s documented patent contribution focuses on signal processing for radio-frequency and microwave applications. The patent describes a circuit architecture designed to support phase shifting across a full 360-degree range.
Collaborations
The patent information identifies Xinyu Liu and Xiaowei Zhu as Gao’s coworkers. The invention is associated with Etra Semiconductor (Suzhou) Co., Ltd.
Conclusion
Jiahui Gao’s patent highlights her work on differential-circuit techniques for phase shifting in radio-frequency microwave systems.
