  • Abstract
    We report an InP HEMT MMIC LNA incorporating dry etched backside ground plane vias with an on-wafer measured peak gain of 9.6 dB at 190 GHz. The 2-stage balanced LNA exhibited over 7 dB gain across a 30 GHz bandwidth. The high gain and high operating frequency of the amplifier is attributed to the lower source inductance provided by the 25 μm dry etched ground vias, the 80 nm T-gate, and the graded In0.80 Ga0.20As channel HEMT
