First we discuss the benefit and challenges of designing a multi-band, multi-mode radio. Therefore, high-efficiency and linear broadband RF power amplifier (PA) design for the microwave and millimeter wave frequencies is obviously becoming more challenging as they evolve from 4G to 5G handset and The advancement in CMOS technology allowing operation at mm-Wave frequencies such as 77, 79 GHz or even higher, will further reduce cost and size of these devices in the coming years.
