I-Low Noise Amplifier Systems, 4~8GHz, Gain 40dB, Noise Figure (NF) 1.1dB

Uhlelo olusha lwesikhulisi somsindo ophansi luthuthukisa ukwamukela kwesignali esebenza kahle. Ezindaweni ezifana nokuxhumana okungenantambo, ukutholwa kwe-radar, ukuzulazula kwesathelayithi, nokulinganisa ukunemba, ukukhuliswa kokuthembeka okuphezulu kwamasignali abuthaka kuseyinselelo ebalulekile yobuchwepheshe. Siyaziqhenya ukwethula isistimu yethu ye-low noise amplifier (LNA) enenzuzo engu-40dB, iletha ukucindezelwa komsindo okukhethekile, ukuzinza kwenzuzo ephezulu, nokusebenza kwe-wideband ukuze sinikeze isisombululo esinokwethenjelwa sokukhulisa isignali yangaphambili kumasistimu kagesi athuthukile. Ngezansi ukubuka okufushane kwezici zayo ezibalulekile nezinhlelo zokusebenza:

Izici Eziyinhloko:

1. Ukusebenza komsindo ophansi kakhulu
Isebenzisa ubuchwepheshe obuthuthukisiwe be-semiconductor kanye nomklamo wesekethe olungiselelwe, isistimu ifinyelela ukusebenza kwesibalo somsindo ohamba phambili embonini, icindezela ngempumelelo umsindo wesistimu ukuze kuqinisekiswe ukwamukela okuzwela okuphezulu kwamasiginali abuthakathaka alungele izinhlelo zokusebenza ezinezidingo eziqinile zesiginali-kuya-kumsindo wesilinganiso.
2. Ukuzuza okuphezulu kanye nokulandelana okuphezulu
I-amplifier ihlinzeka ngenzuzo ephezulu ngenkathi igcina ubuqotho besignali ngobuchwepheshe bokulawula inzuzo yezigaba eziningi, inikela ngebanga eliguquguqukayo elibanzi elifanele izindawo eziyinkimbinkimbi ze-electromagnetic.
3. Ukufakwa kwe-Wideband
Isekela ukusebenza kusuka kumafrikhwensi aphansi kuya kumabhendi wamaza ama-millimeter, uhlelo lunikeza izinketho eziguquguqukayo zefrikhwensi ukuze kuhlangatshezwane nezidingo ezihlukahlukene kwezokuxhumana, i-radar, i-astronomy yomsakazo, nokuningi.
4. Ukuzinza okuphezulu nokuthembeka
Isinxephezelo sezinga lokushisa esakhelwe ngaphakathi namasekhethi avumelana nezimo aqinisekisa ukusebenza okuzinzile ngaphansi kwamazinga okushisa ahlukahlukene nokusebenza isikhathi eside. Idizayini ye-modular evikelwe ngokuphelele icindezela ngempumelelo ukuphazamiseka kwangaphandle, iyenze ifanelekele izindawo ezinokhahlo.
5. Ukuhlanganiswa komsebenzi ohlakaniphile
Izixhumi ezibonakalayo zokulawula idijithali (isb, i-SPI/I2C) zinika amandla ukulungiswa kokuzuzwa kude, ukuqapha isimo, nokuxilongwa kwamaphutha, okusiza ukuhlanganiswa okungenazihibe kumasistimu okuhlola azenzakalelayo noma amathuluzi okwamukela ahlakaniphile.

Izinhlelo zokusebenza ezijwayelekile:

1. Iziteshi eziyisisekelo zokuxhumana okungenantambo: Ithuthukisa ukuzwela umamukeli ezinhlelweni ze-5G/6G, ithuthukisa ukumbozwa konqenqema.
2. Amasistimu wesathelayithi ne-aerospace: Isekela ukwamukelwa kwesignali yesathelayithi kanye nokuhlola kwendawo ejulile ezindaweni ezikude kakhulu, eziphansi ze-SNR.
3. I-radar nempi ye-electronic: Ikhuthaza ukutholwa kwe-echo yethagethi ebuthaka, ithuthukisa ukulungiswa kwe-radar.
4. Amathuluzi esayensi nokulinganisa: Iletha ukukhuliswa kwesignali yokuhlanzeka okuphezulu kwamateleskopu erediyo, ukuhlolwa kwe-quantum, nokuningi.
5. Izinto zikagesi zezokwelapha: Inika amandla ukutholwa kwesignali enembayo ku-MRI namasistimu okuqapha izimpawu ezibalulekile.

I-Qualwave Inc. ihlinzeka ngamasistimu esikhulisi somsindo esimboza i-DC kuya ku-110GHz ibanga lefrikhwensi yezinhlelo zokusebenza ezahlukahlukene. Lesi sihloko sethula uhlelo lwe-4-8GHz LNA olunomsindo ongu-1.1dB.
