0.01-1Ghz inzuzo ephezulu Isikhulisi Samandla Omsindo Ophansi
| Umholi-mw | Isingeniso sokuzuza okuphezulu kwe-Low Noise Power Amplifier |
I-high-gain low-noise amplifier (LNA) esebenza phakathi kwebanga lefrikhwensi engu-0.01 kuya ku-1GHz iyingxenye ebalulekile ezinhlelweni zokuxhumana zesimanje kanye nezinhlelo zokusebenza zokucubungula isignali. Le divayisi iklanyelwe ukuthuthukisa amasignali abuthakathaka ngenkathi yethula umsindo omncane owengeziwe, iqinisekisa ikhwalithi yesiginali ephelele ukuze kuqhutshekwe nokucubungula noma ukuhlaziya.
I-LNA ngokuvamile ihlanganisa izinto ezithuthukisiwe ze-semiconductor nezindlela zokuklama isekethe ukuze kuzuzwe izici zayo zokusebenza ezihlukile. Ukuzuza kwayo, okungaba kukhulu, kuyivumela ukuthi ikhulise amasiginali ngempumelelo ngaphandle kokuhlanekezela okubalulekile, iyenze ifaneleke ukusetshenziswa ezindaweni lapho amandla esignali eyisici esikhawulelayo, njengokuxhumana ngesathelayithi noma ukudluliswa okungenazintambo okude.
Isebenza ngebhendi yefrikhwensi engu-0.01 kuye ku-1GHz ihlanganisa izinhlelo zokusebenza eziningi ezihlanganisa umsakazo we-VHF/UHF, izixhumanisi zama-microwave, nezinye izinhlelo ze-radar. Umkhawulokudonsa obanzi we-amplifier uqinisekisa ukuhambisana namazinga okuxhumana ahlukahlukene kanye nezivumelwano, uthuthukisa ukuguquguquka kwawo kuzo zonke izinkundla ezahlukene kanye namacala okusebenzisa.
Ngokungeziwe ekuzuzeni okuphezulu nomsindo ophansi, okunye ukucaciswa okubalulekile kwalezi zikhulisi kufaka phakathi ukufaniswa kwe-impedance yokufaka nokuphumayo, umugqa, nokuzinza ngaphezu kokuhluka kwezinga lokushisa. Lezi zimfanelo zihlangene zifaka isandla ekuthembekeni nasekuphumeleleni kwazo ekugcineni ubuqotho besignali ngaphansi kwezimo ezihlukahlukene.
Sekukonke, iamplifier yomsindo ophansi enenzuzo ephezulu ngaphakathi kwebanga lefrikhwensi engu-0.01-1GHz ibalulekile ekuthuthukiseni ukuzwela nokusebenza kwezinhlelo zokuxhumana nokubona, okuvumela ukwamukela amasignali acace futhi athembeke kakhudlwana.
