Isihlungi se-LC Low pass LLPF-900/1200-2S

Isakhiwo se-LC i-Low Pass Filter, imodeli ye-LLPF-900/1200-2S, siyisisombululo esincane nesisebenzayo sokuhlunga umsindo ovamise kakhulu ngenkathi sivumela amasignali ovamise kancane ukuthi adlule. Lesi sihlungi senziwe yi-leder-mw, saklanywa ngokunemba engqondweni, sihambisana nezinhlelo zokusebenza lapho ukulinganiselwa kwesikhala kuyisici esibalulekile ngaphandle kokuphazamisa ukusebenza.

Njengoba inebanga lokunqamula imvamisa elisuka ku-900MHz kuya ku-1200MHz, i-LLPF-900/1200-2S icindezela ngempumelelo imvamisa ephezulu engafuneki, iqinisekisa ukudluliswa kwesignali okuhlanzekile ezinhlelweni zokuxhumana, imigqa yedatha, kanye nezifunda ezahlukene ze-elekthronikhi. Ubuncane bayo buyenza ifaneleke kakhulu ekuhlanganisweni kwezakhiwo ze-PCB ezigcwele kakhulu noma lapho ukunciphisa isikhala sebhodi kubalulekile.

Yakhiwe kusetshenziswa izingxenye zekhwalithi ephezulu, kufaka phakathi ama-inductor nama-capacitor akhethwe ngokucophelela, lesi sihlungi esidlula kancane siqinisekisa izici ezinhle kakhulu zokulahlekelwa ukufakwa kanye namakhono okucindezela aqinile. Umklamo we-2-pole uthuthukisa ikhono lesihlungi lokunciphisa ama-harmonics aphezulu nomsindo, okunikeza ukugoqa okuqinile uma kuqhathaniswa nemiklamo ye-single-pole.

Naphezu kobukhulu bayo obuncane, i-LLPF-900/1200-2S igcina imininingwane kagesi ehlaba umxhwele, njengokulahlekelwa okuphansi kokubuya ngaphakathi kwe-passband kanye nokwenqatshwa okuphezulu kokuphuma kwe-band. Lokhu kuqinisekisa ukuwohloka okuncane kwesignali yebanga lemvamisa elihlosiwe ngenkathi kuvimbela ngempumelelo amaza angafuneki angaphazamisa ukusebenza kwesistimu.

Ngamafuphi, i-leder-mw LCstructure Low Pass Filter LLPF-900/1200-2S ivelele njengokukhetha okuguquguqukayo nokuthembekile kwabaklami abafuna ikhambi elisebenza kahle nelonga isikhala lezidingo zokuhlunga eziphansi ezinhlotsheni eziningi zezinhlelo zokusebenza ze-elekthronikhi nezokuxhumana.
