Title: Xinyu Liu and Phase-Shifting Circuit Innovation
Introduction
Xinyu Liu is an inventor associated with Suzhou, China, and Etra Semiconductor (Suzhou) Co., Ltd. Her patent work concerns phase-shifting technology for radio-frequency and microwave systems.
Latest Patents
Liu is associated with 1 patent: “Phase-Shifting Circuits and Radio Frequency Microwave Systems.” The invention describes a circuit that splits an input signal into two differential signals, processes them through separate differential signal channels, and combines the resulting phase-shifted signals into an output. The channels can attenuate signals or transform their quadrants, enabling the output’s phase difference from the input to fall within a range of 0 to 360 degrees.
Career Highlights
Liu’s disclosed patent reflects work on signal processing architectures for radio-frequency and microwave applications. The described design uses coordinated signal splitting, channel processing, and synthesis to achieve phase shifting.
Collaborations
Liu’s patent-related work is associated with Etra Semiconductor (Suzhou) Co., Ltd. Her listed coworkers include Xiaowei Zhu and Jun Chen.
Conclusion
Xinyu Liu’s patent describes a differential-circuit approach to phase shifting that supports radio-frequency and microwave systems.
