Abstract :
A 20 GHz band 135 K (NF=1.66dB) low-noise HEMT amplifier with 38 dB gain has been developed. This was achieved by extremely low-loss input circuits, accurate device characterization method with a strip line tuner and a compact cooling system. The amplifier is cooled to -55°C by a Peltier-cooling unit which consumes only 60 watts.
