Ostensibly, one key component of any receiver chain is the low-noise amplifier (LNA) coming off the antennas. Since the signal at that point is comparatively weak, good gain and noise performance are necessary.

This paper describes an amplifier circuit which yields very low noise factor, consisting of a grounded-cathode triode followed by a grounded-grid triode. The combination is entirely noncritical and provides the low noise factor of a triode with the high amplification and stability of a pentode.
