Abstract: Ultra Low Noise Gals PET amplifiers incorporati& source inductance feedback to obtain low input VSWR have been deacribed. The measured average noise temperature of 52K - (~oise Figure 0.7d~) at room temperature of the L-Band Amplifier reduces to 14K (Noise Figure 0.2dB) when cooled to a tempera- . ture of 24K. The C-Band Amplifier has an average noiae temperature of 120K (~oise Figure 1,Sd~) at room temperature.
