Isesengura ryimbitse ryamahame yimirimo nuburyo bukoreshwa bwa duplexers, triplexers na quadplexers

Muri sisitemu ya kijyambere itumanaho rya simusiga, duplexers, triplexers na quadplexers nibyingenzi byingenzi kugirango bigerweho no kohereza ibimenyetso byinshi. Bahuza cyangwa batandukanya ibimenyetso nibice byinshi byinshyi, byemerera ibikoresho kohereza no kwakira imirongo myinshi icyarimwe mugihe mugabana antene. Nubwo itandukaniro ryamazina nuburyo, amahame shingiro yabo arasa, hamwe itandukaniro nyamukuru numubare nuburemere bwimirongo yumurongo yatunganijwe.

Duplexer

Duplexer igizwe nayunguruzo ebyiri zisangiye icyambu rusange (mubisanzwe antene) kandi zikoreshwa mugushyira mubikorwa imirimo yo kohereza (Tx) no kwakira (Rx) kubikoresho bimwe. Ikoreshwa cyane cyane muri sisitemu yo kugabana duplex (FDD) kugirango ikumire kwivanga mugutandukanya kohereza no kwakira ibimenyetso. Duplexers isaba urwego rwo hejuru rwo kwigunga, mubisanzwe hejuru ya 55 dB, kugirango barebe ko ibimenyetso byanduye bitagira ingaruka kumyumvire yabakiriye.

Urugendo

Urugendo rugizwe na filtri eshatu zisangiye icyambu. Yemerera igikoresho gutunganya ibimenyetso biva mumirongo itatu itandukanye icyarimwe kandi ikoreshwa kenshi muri sisitemu yitumanaho ikeneye gushyigikira imirongo myinshi icyarimwe. Igishushanyo cya triplexer gikeneye kwemeza ko passband ya buri muyunguruzi idapakira izindi filteri kandi igatanga ubwigunge buhagije kugirango hirindwe kwivanga hagati yumurongo wumurongo.

Quadplexer

Quadplexer igizwe na filteri enye zisangiye icyambu. Iyemerera igikoresho gutunganya ibimenyetso biva mumirongo ine itandukanye yumurongo icyarimwe kandi birakwiriye kuri sisitemu yitumanaho igoye isaba gukora neza cyane, nka tekinoroji yo guteranya ibintu. Igishushanyo mbonera cya quadplexer ni ndende cyane kandi igomba kuba yujuje ibisabwa byambukiranya imipaka kugira ngo ibimenyetso biri hagati yumurongo wa interineti bitavangira.

Itandukaniro nyamukuru

Umubare wumurongo wumurongo: Duplexers itunganya imirongo ibiri yumurongo, triplexers itunganya imirongo itatu yumurongo, na quadplexers itunganya imirongo ine yumurongo.

Igishushanyo mbonera: Nkuko umubare wumurongo wa frequency wiyongera, igishushanyo mbonera hamwe nibisabwa byo kwigunga nabyo byiyongera bikwiranye.

Ikoreshwa rya porogaramu: Duplexer ikoreshwa kenshi muri sisitemu yibanze ya FDD, mugihe triplexers na quadplexers zikoreshwa muri sisitemu yitumanaho igezweho ikeneye gushyigikira imirongo myinshi yumurongo icyarimwe.

Gusobanukirwa nuburyo bukora nuburyo butandukanye bwa duplexers, triplexers, na quadplexers ningirakamaro mugushushanya no gutezimbere sisitemu yitumanaho ridafite umugozi. Guhitamo ubwoko bukwiye bwa multiplexer burashobora kunoza neza sisitemu yo gukoresha no gukoresha itumanaho.
