0.03-1Ghz I-Front End Receiver Isamukeli Samandla Omsindo Ophansi Ngenzuzo engu-40dB
| Umholi-mw | Isingeniso se-0.03-1Ghz Low Noise Amplifier Ngenzuzo engu-40dB |
Sethula ukuqamba okusha kubuchwepheshe bokukhulisa isignali: isikhulisi somsindo ophansi esingu-0.03-1GHz esinenzuzo emangazayo engu-40dB. Idizayinelwe izinhlelo zokusebenza ezidinga ukusebenza okuphezulu nokuthembeka, lesi sikhulisamandla siyisixazululo esiphelele sokuthuthukisa amasiginali abuthaka ezindaweni eziphansi.
Lesi sikhulisamandla esinomsindo ophansi sinebanga lemvamisa le-0.03GHz ukuya ku-1GHz futhi siklanyelwe ukuhlinzeka ngokusebenza okuhle kakhulu ezinhlelweni ezihlukene ezihlanganisa ezokuxhumana, ukusakaza kanye nocwaningo lwesayensi. Isibalo sayo somsindo ophansi siqinisekisa ukuncishiswa kwesignali okuncane, okuholela ekudlulisweni kwesignali okucacile nokunembe kakhudlwana.
Esinye sezici ezivelele ze-amplifier ukuzuza kwayo okuhle kakhulu kwe-40dB, okuthuthukisa kakhulu amandla wesiginali yokufaka. Lokhu kuyenza ilungele amasistimu adinga ukuzwela okuthuthukisiwe kanye nesilinganiso esithuthukisiwe sesignali-to-noise. Kungakhathaliseki ukuthi ucubungula amasignali e-RF, umsindo, noma ezinye izinhlelo zokusebenza ezinemvamisa ephansi, lesi sikhulisamandla siletha amandla adingekayo ukuze kuqinisekiswe ukusebenza kahle.
Ukwengeza, idizayini ehlangene ye-amplifier yomsindo ophansi engu-0.03-1GHz ikuvumela ukuthi ihlanganiswe kalula kumasistimu akhona ngaphandle kokuthatha indawo ebalulekile. Ukwakhiwa kwayo okuqinile kuqinisekisa ukuqina nokuphila isikhathi eside, okwenza kube ukukhetha okuthembekile kwezicelo zezohwebo nezimboni.
Kafushane, isikhulisi somsindo ophansi esingu-0.03-1GHz esinenzuzo engu-40dB iyisixazululo esisezingeni eliphezulu kunoma ubani ofuna ukuthuthukisa ikhwalithi yesiginali nokusebenza ezinhlelweni zefrikhwensi ephansi. Izwa umehluko ekucaceni nasekuthembekeni ngale amplifier yesimanje futhi uthathe amaphrojekthi akho uwayise phezulu.
