   He also presented a Ka band low-noise amplifier in 90-nm CMOS technology, achieving 19 dB peak gain and 3 dB noise figure. It featured a thin-film microstrip line and gain-boosting circuits, resulting in a 20% gain improvement and 27% noise reduction with low power consumption and compact size. [13]

3. 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.

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 ...

5. Personal sound amplification product - Wikipedia

   en.wikipedia.org/wiki/Personal_sound...

   The amplifier (an electronic circuit) increases the amplitude of the electric signal using a power source (battery). The speaker converts the amplified electric signal back into a sound wave. The volume (gain) control is used to adjust the amount of amplification applied to the electric signal and thus, indirectly, controls the sound volume.

6. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   The LNB is a combination of low-noise amplifier, frequency mixer, local oscillator and intermediate frequency (IF) amplifier. It serves as the RF front end of the satellite receiver, receiving the microwave signal from the satellite collected by the dish, amplifying it, and downconverting the block of frequencies to a lower block of ...

7. Valve RF amplifier - Wikipedia

   en.wikipedia.org/wiki/Valve_RF_amplifier

   (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 ...

9. Distributed amplifier - Wikipedia

   en.wikipedia.org/wiki/Distributed_Amplifier

   The design of the distributed amplifiers was first formulated by William S. Percival in 1936. [1] In that year Percival proposed a design by which the transconductances of individual vacuum tubes could be added linearly without lumping their element capacitances at the input and output, thus arriving at a circuit that achieved a gain-bandwidth product greater than that of an individual tube.
