2. Antenna amplifier - Wikipedia

   en.wikipedia.org/wiki/Antenna_amplifier

   In electronics, an antenna amplifier (also: aerial amplifier or booster) is a device that amplifies an antenna signal, usually into an output with the same impedance as the input impedance. Typically 75 ohm for coaxial cable and 300 ohm for twin-lead cable. An antenna amplifier boosts a radio signal considerably for devices that receive radio ...

3. 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. 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. 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.

8. AN/ARC-5 - Wikipedia

   en.wikipedia.org/wiki/AN/ARC-5

   Audio frequency receiver output and modulator sidetone impedance for the ARA/ATA and the AN/ARC-5 is 300 to 600 ohms. In the SCR-274-N "-A" version, the receiver and modulator impedance is 4000 ohms, while "-B" and later version units have a 250 ohm tap on the AF transformers which can be connected.

9. Line level - Wikipedia

   en.wikipedia.org/wiki/Line_level

   Line outputs usually present a source impedance of from 100 to 600 ohms. The voltage can reach 2 volts peak-to-peak with levels referenced to −10 dBV (300 mV) at 10 kΩ . The frequency response of most modern equipment is advertised as at least 20 Hz to 20 kHz, which corresponds to the range of human hearing .
