Advanced Supply Modulator Design for 6G FR3 RF Power Amplifiers

This talk presents next-generation supply modulation technologies for 6G RF power amplifiers, including various approaches such as analog envelope tracking, digital envelope tracking, symbol power tracking, and related techniques. Compared to 5G NR, 6G wireless communication demands significantly wider channel bandwidths and much higher linearity at emerging upper-mid-band (FR3) frequencies, which severely degrades the power efficiency of conventional linear PAs. To address these challenges while maintaining high efficiency, this seminar introduces advanced PA supply modulation techniques tailored for wideband, high-linearity 6G FR3 applications.
