  • Abstract
    A GaAs monolithic variable gain amplifier based on segmented dual-gate FETs is described. Design, fabrication, and performance of the MMIC are outlined. Special emphasis is given to the modeling of the active devices. It is shown that a simple equivalent circuit is sufficient to accurately model multiple segmented dual-gate FETs at least up to X-band.
