  • Abstract
    A two-stage 12 GHz LNA has been realised as a lumped element MMIC on GaAs substrates using In0.25Ga0.75As channel PM-MODFETs. The gain is >17 dB and noise figure is <1.25 dB. Input (output) match is better than -21 DB (-14 qB). The MMIC design includes reactive feedback by source inductances and makes use of optimised gate widths for broad noise circles and easy impedance match.
