A 1–20 GHz Distributed, Stacked SiGe Power Amplifier

This paper presents a wideband distributed power amplifier that operates from 1–20 GHz. The peak output power is 19.5 dBm, with a peak PAE of 28% at 1 GHz. The power amplifier utilizes a distributed amplifier topology with artificial transmission lines, as well as transistor stacking, to achieve high output power and wide bandwidth. For the amplifier core power cells, a stack-up of four SiGe HBTs was used to distribute the maximum voltage swing across the amplifier. This power amplifier, designed in a 90 nm SiGe BiCMOS platform, occupies an area of $\mathbf{1.95}\times \mathbf{1.3}\mathbf{mm}^{2}$.
