  • Abstract
    This paper proposes a new systematic approach to the noise-figure (NF) sensitivity analysis of MMIC low-noise amplifiers (LNA) regarding device-structure parameters such as gate-recess variation . A full-monolithic uniplanar two-stage LNA with an extremely low NF of 2.8 dB at 50 GHz is fabricated and analyzed using this new method. A comparative study reveals that the gate recess variation in the fabricated HEMTs causes no substantial NF variation in the MMIC-LNAs.<>
