Abstract :
Junction FET´s with high gm, low feedback capacitance and low noise figures at 100 MHz are currently available. When operated in the common gate mode as RF amplifiers, they can provide high gain with good stability factors and almost an optimum antenna match with no input tuned circuit. In addition, tuners which require no shielding for RF stability are easily constructed. Overall receiver noise figures of less than 6 dB are readily obtainable.
