This paper discusses various supply-modulated power amplifier (SM-PA) architectures for amplifying high peak-to-average power ratio (PAPR) signals, and implementations of such amplifiers in GaN technology in the X-band frequency range, towards the high-frequency carriers and bandwidths for 5G. Specifically, 10-W MMIC GaN PAs with greater than 60% efficiency at 10GHz with efficient GaN supply modulators for signals with envelope bandwidths of several 100 MHz and PAPR up to 10dB are detailed… CONTINUE READING
