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.

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

   A universal LNB has a switchable local oscillator frequency of 9.75/10.60 GHz to provide two modes of operation: low band reception (10.70–11.70 GHz) and high band reception (11.70–12.75 GHz). The local oscillator frequency is switched in response to a 22 kHz signal superimposed on the supply voltage from the connected receiver.

6. 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.

7. At Home (store) - Wikipedia

   In 2014, Garden Ridge converted all stores to the At Home brand and floorplan. [7] The rebranding project changed the use of orange color for advertising to a soft grey and blue, and added a house symbol for the "o" in At Home. [8] The rebranding cost around $20 million. [8] At Home publicly filed an S-1 on September 4, 2015, to go public. [9]
