摘要: This paper describes an amplifier circuit which yields very low noise factor, consisting of a grounded-cathode triode followed by grounded-grid triode. The combination is entirely noncritical and provides the factor with high amplification stability pentode. Noise factors averaging 0.25 db at carrier frequency 6 Mc. 1.35 30 have been achieved. Typical details are given.
