2020-5-20 Abstract: This article presents the design of a highly linear high-power silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) 802.11ac/aχ wireless local area network (WLAN) power amplifiers (PAs). The challenges associated with electrothermal effects on the dynamic operation of WLAN PAs are first discussed.
