Ang low noise amplifier ay isang amplifier na may napakababang noise figure, na ginagamit sa mga circuit upang palakasin ang mahinang signal at bawasan ang ingay na ipinakilala ng amplifier.

Ito ay karaniwang ginagamit bilang high-frequency o intermediate frequency preamplifier ng iba't ibang Radio receiver, at ang amplification circuit ng high-sensitivity electronic detection equipment.Ang isang mahusay na Low-noise amplifier ay kailangang palakasin ang signal habang gumagawa ng pinakamababang ingay at distortion hangga't maaari.

Ang mga sumusunod ay ang pangunahing Mga Tampok at aplikasyon ng mga low noise amplifier:

1. Makakuha ng amplification: Maaaring palakasin ng LNA ang mahinang input signal sa isang sapat na antas para sa kasunod na pagpoproseso ng circuit o system.Sa wireless na komunikasyon, ang natanggap na signal ay kadalasang napakahina, at sa pamamagitan ng amplification effect ng LNA, ang signal ay maaaring mapahusay sa isang maaasahang antas upang magbigay ng kasunod na pagproseso at demodulation.
2. Bawasan ang ingay ng system: Nagsusumikap ang LNA na bawasan ang pagpasok ng karagdagang ingay habang pinapalakas ang signal.Napakahalaga ng ingay para sa pagganap ng mga wireless na sistema ng komunikasyon dahil maaari nitong itago ang mga signal at bawasan ang ratio ng signal-to-noise ng system.Binabawasan ng low noise amplifier ang ingay ng system sa pamamagitan ng pagliit ng noise figure sa pamamagitan ng paggamit ng na-optimize na disenyo ng circuit at mababang ingay na materyales.
3. Pagpapabuti ng dynamic range ng system: Ang isa pang function ng LNA ay palawakin ang dynamic range ng system.Ang dinamikong hanay ay tumutukoy sa kakayahan ng isang system na pangasiwaan ang parehong malakas at mahinang signal nang sabay-sabay.Ang mga low noise amplifier ay kayang humawak ng mas mahihinang signal nang walang overloading o distortion dahil sa mas malalakas na signal.Nagbibigay-daan ito sa system na gumana nang epektibo sa mga kapaligiran na may malaking hanay ng mga pagkakaiba sa lakas ng signal.

Ang mga pangunahing larangan ng aplikasyon ng LNA ay ang wireless na komunikasyon, kagamitang medikal, mga instrumento sa pagsukat, radar, komunikasyon sa satellite, atbp.
