Low Noise Amplifiers

Low noise amplifier thumnail picture
"Cooled,low noise microwave FET amplifiers are used extensively in radio telescopes,sattelite earth stations,and radar systems to minimize noise added to the signal by the receiver...." Quoted from:

A number of low noise amplifiers were made here using the Weinreb design in the schematic, some used the Mitsubishi MGF 1412 GaAs FET.

Dr. Valk went to S.E.D. systems in Saskatchewan after completing his studies here.
