RF BroadBand EMC Low Noise Amplifiers
In fersterker mei leech lûd is in fersterker mei in heul leech lûdsfiguer, brûkt yn circuits om swakke sinjalen te fersterkjen en it lûd yntrodusearre troch de fersterker te minimalisearjen.
It wurdt oer it algemien brûkt as de hege-frekwinsje as tuskenfrekwinsje preamplifier fan ferskate Radio ûntfanger, en de fersterking circuit fan hege-sensitive elektroanyske detectie apparatuer.In goede Low-noise-fersterker moat it sinjaal fersterkje wylst se sa leech mooglik lûd en ferfoarming produsearje.
It folgjende binne de haadfunksjes en tapassingen fan fersterkers mei leech lûd:
1. Gain amplification: LNA kin fersterkje swakke ynfier sinjalen nei in foldwaande nivo foar folgjende circuit of systeem ferwurkjen.Yn draadloze kommunikaasje is it ûntfongen sinjaal faaks heul swak, en troch it fersterkingseffekt fan LNA kin it sinjaal ferbettere wurde nei in betrouber nivo om folgjende ferwurking en demodulaasje te leverjen.
2. Reduce systeem lûd: LNA stribbet nei in minimalisearje de ynfiering fan ekstra lûd wylst it fersterkjen fan it sinjaal.Lûd is krúsjaal foar de prestaasjes fan draadloze kommunikaasjesystemen, om't it sinjalen kin maskerje en de sinjaal-to-lûd-ferhâlding fan it systeem kin ferminderje.In fersterker mei leech lûd ferminderet systeemlûd troch it minimalisearjen fan lûdsfiguer troch it brûken fan optimalisearre circuitûntwerp en materialen mei leech lûd.
3. It ferbetterjen fan it dynamyske berik fan it systeem: In oare funksje fan LNA is om it dynamyske berik fan it systeem út te wreidzjen.Dynamysk berik ferwiist nei it fermogen fan in systeem om sawol sterke as swakke sinjalen tagelyk te behanneljen.Fersterkers mei lege lûd kinne swakkere sinjalen omgean sûnder oerladen of ferfoarming fanwege sterkere sinjalen.Dit stelt it systeem yn steat om effektyf te wurkjen yn omjouwings mei in grut oanbod fan ferskillen yn sinjaalsterkte.
De wichtichste tapassingsfjilden fan LNA binne draadloze kommunikaasje, medyske apparatuer, mjitynstruminten, radar, satellytkommunikaasje, ensfh.
