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.
Quite Universal Circuit Simulator (Qucs) is a free-software electronics circuit simulator software application released under GPL.It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit.
An RF amplifier, often called the low-noise amplifier (LNA). Its primary responsibility is to increase the sensitivity of the receiver by amplifying weak signals without contaminating them with noise, so that they can stay above the noise level in succeeding stages. It must have a very low noise figure (NF). The RF amplifier may not be needed ...
Also called a low-noise block, [1] [2] low-noise converter (LNC), or even low-noise downconverter (LND), [3] the device is sometimes inaccurately called a low-noise amplifier (LNA). [ 4 ] The LNB is a combination of low-noise amplifier, frequency mixer , local oscillator and intermediate frequency (IF) amplifier.

The noise factor (a linear term) is more often expressed as the noise figure (in decibels) using the conversion: = The noise figure can also be seen as the decrease in signal-to-noise ratio (SNR) caused by passing a signal through a system if the original signal had a noise temperature of 290 K. This is a common way of expressing the noise ...
