Low-Noise Amplifiers on Magnetotransistors Below 40 GHz

Chapter

Abstract

The results of theoretical researches of the physical principles of functioning and ways of design of low-noise amplifiers on the basis of transistor-magnetic structures, which can be promising for satellite communication systems with a raised density of information channels, are considered. Directions of noise decrease (the noise factor below 3.5 dB), and management of the selective properties in magnetotransistor amplifiers with a dynamic range not less than 70 dB, with a minimum level of signal − 156 dBW, and with a saturation signal above − 70 dBW is investigated.
