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. NE5532 - Wikipedia

   en.wikipedia.org/wiki/NE5532

   A genuine Signetics NE5532N in PDIP package, made in 1990, on a modem board A Texas Instruments SA5532A in SOIC package on an audio distribution amplifier board . The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979.

4. Naim Audio amplification - Wikipedia

   FBARs can also be integrated with power amplifiers (PA) or low noise amplifiers (LNA) to form a module solution with the related electronic circuitry. Although monolithic integrated of FBARs on the same substrate with the electronic circuitry like CMOS has been demonstrated it requires several additional process steps and mask layers on top of ...

7. 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.
