2. Low-noise amplifier - Wikipedia

   en.wikipedia.org/wiki/Low-noise_amplifier

   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.

   The noise power at the output of the amplifier chain consists of four parts: The amplified noise of the source The output referred noise of the first amplifier amplified by the second and third amplifier ()

4. Tower Mounted Amplifier - Wikipedia

   en.wikipedia.org/wiki/Tower_Mounted_Amplifier

   A Tower Mounted Amplifier (TMA), or Mast Head Amplifier (MHA), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity ; in other words the mobile mast is able to receive ...

6. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   The low-noise amplifier section of the LNB amplifies this weak signal while adding the minimum possible amount of noise to the signal. The low-noise quality of an LNB is expressed as the noise figure (or sometimes noise temperature). This is the signal-to-noise ratio at the input divided by the signal-to-noise ratio at the output.

7. Noise figure - Wikipedia

   en.wikipedia.org/wiki/Noise_figure

   The noise factor is defined as the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature T 0 (usually 290 K). The noise factor is thus the ratio of actual output noise to that which would remain if the device itself did not introduce noise, which ...

9. Instrumentation amplifier - Wikipedia

   en.wikipedia.org/wiki/Instrumentation_amplifier

   Feedback-free instrumentation amplifier is the high-input-impedance differential amplifier designed without the external feedback network. This allows reduction in the number of amplifiers (one instead of three), reduced noise (no thermal noise is brought on by the feedback resistors) and increased bandwidth (no frequency compensation is needed).
