A compact WR-1.5 low-noise amplifier circuit has been developed, based on a grounded coplanar waveguide technology utilizing 20 nm metamorphic high electron mobility transistors. The realized six-stage LNA TMIC achieved a maximum gain of 15.4 dB at 576 GHz and more than 10 dB in the frequency range from 555 to 619 GHz. The fabricated LNA module demonstrates a small-signal gain of 14.1 dB at 600 GHz and a room temperature (T = 293 K) noise figure of 15 dB at the frequency of operation.
