MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202617016817 A) filed by Vanchip (TIANJIN) Technology Co. Ltd., Tianjin, China, on Feb. 16, for 'radio frequency front-end module for optimizing dynamic error vector magnitude and electronic device.'
Inventor(s) include Li, Hao; Zhang, Jun; Chen, Lufeng; and Li, Junfeng.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "Disclosed in the present invention is a radio frequency front-end module for optimizing dynamic error vector magnitude, comprising at least one transmitting channel. Each transmitting channel comprises a driving amplifier, a first bias circuit, a first dynamic power supply, a power amplifier, a second bias circuit, a second dynamic power supply, a logic circuit and a TX timer; upon receiving a TX instruction, the logic circuit controls the transmitting channel to enter a TX working mode, and the TX timer starts timing; and on the basis of a plurality of set time periods, at least one of the first dynamic power supply and the second dynamic power supply outputs dynamic power supply voltages that sequentially increase or decrease, and provides the dynamic power supply voltages to the first bias circuit and/or the second bias circuit, so as to dynamically compensate for the output power change caused by the temperature change of a circuit, ensuring that the dynamic error vector magnitude meets higher requirements."
The patent application was internationally filed on June 16, 2024, under International application No.PCT/CN2024/099469.
