A low-noise amplifier (LNA) is an electronic component that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio (SNR). Any electronic amplifier will increase the power of both the signal and the noise present at its input, but the amplifier will also introduce some additional noise.

Polaris Fashion Place is a two level shopping mall and surrounding retail plaza serving Columbus, Ohio, United States.The mall, owned locally by Washington Prime Group, is located off Interstate 71 on Polaris Parkway in Delaware County just to the north of the boundary between Delaware and Franklin County.
The LM358 is a low-power dual operational amplifier integrated circuit, originally introduced by National Semiconductor. [1] It uses a single power supply from +3 to +30 volts for V CC (though some variants go higher, such as 36 volts for the LM358B). Input voltage can range from −0.3 volts to V CC.
Bell Labs [b] is an American industrial research and development (R&D) company, currently operating as a subsidiary of Finnish technology company Nokia.With a long history, Bell Labs is credited with the development of radio astronomy, the transistor, the laser, the photovoltaic cell, the charge-coupled device (CCD), information theory, the Unix operating system, and the programming languages ...
(This is the reason for the relatively high noise resistance of the EF86 in the above example.) Thus, tubes with low noise at high frequency do not necessarily have low noise in the audio frequency range. For special low-noise audio tubes, the frequency at which 1/f noise takes over is reduced as far as possible, maybe to approximately a ...
