I-Low Noise Amplifier (LNA) isikhulisi esinomsindo ophansi kakhulu. Isetshenziselwa kakhulu ukukhulisa amasiginali abuthakathaka ngenkathi kunciphisa ukuphazamiseka komsindo ukuze kuthuthukiswe isilinganiso sesignali-kumsindo. Ivamise ukubekwa ngaphambili ekugcineni kwesistimu yokwamukela umsakazo, njengangemuva kothi, ukuze kukhuliswe amasignali abuthaka atholwe emoyeni.
Izici:
1.Umfanekiso Womsindo Ophansi: Isici esiyinhloko se-Low Noise Amplifier isibalo saso somsindo ophansi kakhulu (Umfanekiso Womsindo, NF). Lapho isibalo somsindo siphansi, ukuphazamiseka komsindo okuncane okwethulwa yi-amplifier, okuholela esilinganisweni esiphezulu sesignali-kuya-nomsindo.
2.Inzuzo Ephezulu: Ukuze kukhuliswe ngempumelelo amasiginali abuthakathaka, Isikhulisi Somsindo Ophansi sivamise ukuba nenzuzo ephezulu, engakhuphula ngokuphawulekayo i-amplitude yesiginali.
3.Umkhawulokudonsa obanzi: Izikhulisamsindo eziningi eziphansi zenzelwe ukuthi zibe ibhande elibanzi, elikwazi ukuphatha amasiginali kububanzi obubanzi befrikhwensi.
4.Ukuzinza Okuhle: Isikhulisi Somsindo Ophansi sidinga ukuba nokuzinza okuhle ukuze sigweme ukunyakaziswa lapho sisebenza kumafrikhwensi aphezulu.
I-Low Noise Amplifiers isetshenziswa kabanzi kwezokuxhumana okungenantambo, ukuxhumana ngesathelayithi, irada, izindlela zokuphikisa zikagesi, isayensi yezinkanyezi yomsakazo, neminye imikhakha.
I-Qualwave ihlinzeka ngezikhulisi zomsindo ophansi ezihlukahlukene kusukela ku-4K kuya ku-260GHz, futhi isibalo somsindo singase sibe phansi njengo-0.7dB.
Sethula enye yazo, ngamafrikhwensi asuka ku-9KHz ukuya ku-3GHz, inzuzo engu-43dB, isibalo somsindo esingu-3dB, i-P1dB ka-16dBm.

I-Qualwave iqongelele iminyaka yokuhlangenwe nakho ocwaningweni nasekuthuthukisweni kwezikhulisamandla zomsindo ophansi, ezingafinyelela ukukhiqizwa ngobuningi kanye nocwaningo olwenziwe ngokwezifiso kanye nentuthuko ngokuya ngezidingo zamakhasimende.
Siyakwamukela ukushiya umlayezo ukuze uthole ulwazi olwengeziwe.
