Latest Patents

One of Jifeng Chen's latest patents is titled "Systems and methods for improving output stability of a radio frequency power amplifier by gain compensation and correction." This invention outlines a system that obtains an initial radio frequency signal to be amplified by the RFPA. The system generates a compensated radio frequency signal by performing a gain compensation operation based on a preset compensation rule and a set of compensation parameters, which include the supply voltage of the RFPA and the transistor junction temperature. Furthermore, the system generates a corrected radio frequency signal through a non-linear correction operation, which is then transmitted to the RFPA.

Another notable patent is the "Radio frequency power amplifier control device." This device includes an input signal processing module that processes an input signal into two separate signals. One signal is designated for signal detection, while the other is used for signal amplification. The device also features a delay module that ensures the second signal and the control signal reach the adjustment module simultaneously.
