  • Abstract
    This paper presents a 33 dBm, 3-stage stacked GaAs pHEMT power amplifier at 22GHz with on-chip matching networks. The circuit topology is explained, and interstage matching techniques are simulated to investigate their aptitude to achieve interstage matching for the individual transistors. Special care was put on the design of a very compact layout with on-chip matching networks. Simulation results are presented and the stacking benefits are outlined.
