A 50nm MHEMT millimeter-wave MMIC LNA with wideband noise and gain performance

A 50nm MHEMT millimeter-wave MMIC low noise amplifier with state-of-the-art performance is reported. The 3-stage LNA exhibits on-wafer noise figure (NF) as low as 1.6dB with 25dB gain at 80GHz, and also shows unprecedented wideband performance, with 20dB minimum gain across the 30-100GHz band and NF <;2.5dB over the 43-90GHz band. An LNA packaged in a WR-12 module has flange NF of 2.0dB over 74-80GHz and NF <;2.6dB with 27 ± 2dB gain across the full 60-90GHz waveguide band.
