L-Band Low Noise Transistor Amplifier
IETE Journal of Research, 1974This paper describes an L-Band low noise transistor preamplifier fabricated in micro-stripline configuration for microwave receiver for troposcatter propagation measurements. The amplifier provides a gain of 15.5±0.5 dB and noise figure of 4±0.5 dB in the frequency range of 1 to 2 GHz. The output power of 1 dB gain compression is zero dBm.

HF Cryogenic Low Noise Amplifier
AIP Conference Proceedings, 2004AL/DTA and IN/SNEC had developed a demonstrator of an RF cryogenic LNA in order to improve the links budget of remote sensing earth station. Working in X band, the cooled LNA allows to reduce efficiently the size of the antennas. So, this solution offers a cheaper alternative to the actual technology used in this area.This demonstrator operates at 80 K

Low-noise backward-wave amplifiers
IRE Transactions on Electron Devices, 1957The characteristics of backward-wave amplifiers are briefly reviewed and related to general receiver problems which exist in broad-band high-power systems. It is emphasized that a backward-wave amplifier of sufficiently low noise figure offers potential solution to several of these problems and would be more useful in some cases than a conventional low-

Review of Scientific Instruments, 1958
A low-noise 30-Mc amplifier with Western Electric Type 416B triodes used in a cascode circuit is described. The theoretical noise figure of the amplifier, with the optimum value of source resistance, is 1.06 or 0.26 db. The amplifier is being used to study noise in semiconductors.
