Abstract
This article presents a two-chip supply modulation architecture for efficient RF power amplification using a fully switched-mode supply modulator (SM) and a linear-assisted hybrid SM to support simultaneous transmission on long-term evolution (LTE) and 5G bands. The designed fully switched- mode SM consists of a fast switching buck converter and a slow switching buck converter, and it achieves 88.2% peak efficiency and a low receiver (RX) band noise of −140 dBm/Hz at the SM output. The fully switch
