Kuongorora kwakadzama kwenheyo dzekushanda uye mashandisirwo e duplexers, triplexers uye quadplexers

Mumasystem emazuva ano ekutaurirana asina waya, maduplexer, matriplexer nemaquadplexer zvinhu zvakakosha passive passive kuti signal signal isvike pa multi-band. Anosanganisa kana kuparadzanisa masignal kubva kuma frequency band akawanda, zvichibvumira michina kutumira nekugamuchira ma frequency band akawanda panguva imwe chete vachigovana ma antenna. Pasinei nekusiyana kwemazita nemaumbirwo, misimboti yavo mikuru yakafanana, musiyano mukuru uri huwandu uye kuoma kwema frequency band anogadziriswa.

Duplexer

Duplexer ine mafirita maviri ane chiteshi chimwe chete (kazhinji antenna) uye anoshandiswa kuita mabasa ekutumira (Tx) nekugamuchira (Rx) pachishandiso chimwe chete. Inonyanya kushandiswa mumasystem ekuparura ma frequency duplex (FDD) kudzivirira kupindirana nekuparadzanisa masaini ekutumira nekugamuchira. Ma duplexer anoda huwandu hwakanyanya hwekuzviparadzanisa, kazhinji kupfuura 55 dB, kuti ave nechokwadi chekuti chiratidzo chinotumirwa hachikanganisi kunzwa kwemugamuchiri.

Triplexer

Triplexer ine mafirita matatu ane chiteshi chimwe chete. Inobvumira mudziyo kugadzirisa masaini kubva kumabhendi matatu akasiyana efrequency panguva imwe chete uye inowanzoshandiswa mumasisitimu ekutaurirana anoda kutsigira mabhendi akawanda efrequency panguva imwe chete. Dhizaini yetriplexer inofanirwa kuve nechokwadi chekuti passband yefirita yega yega haitore mamwe mafirita uye inopa kupatsanurwa kwakakwana kudzivirira kupindirana pakati pemabhendi efrequency.

Quadplexer

Chinotenderera chine mafirita mana ane chiteshi chimwe chete. Chinobvumira mudziyo kugadzirisa masaini kubva kumabhendi mana akasiyana panguva imwe chete uye chakakodzera masisitimu akaomarara ekutaurirana anoda kushanda zvakanaka kwespectral, senge tekinoroji yekutakura. Kuoma kwedhizaini yechinotenderera kwakakwira uye kunoda kusangana nezvinodiwa zvakasimba zvekupatsanurana kuti ive nechokwadi chekuti masaini ari pakati pemabhendi emafriza haapindirani.

Misiyano mikuru

Huwandu hwemabhendi emafrequency: Maduplexer anogadzira mabhendi maviri emafrequency, matriplexer anogadzira mabhendi matatu emafrequency, uye maquadplexer anogadzira mabhendi mana emafrequency.

Kuomarara kwedhizaini: Sezvo huwandu hwemabhendi emafrequency huchiwedzera, kuomarara kwedhizaini uye zvinodiwa zvekuzviparadzanisa zvinowedzerawo zvinoenderana.

Maitiro ekushandisa: Maduplexer anowanzo shandiswa mumasystem ekutanga eFDD, nepo matriplexer nemaquadplexer achishandiswa mumasystem ekukurukurirana epamusoro anoda kutsigira mafrequency band akawanda panguva imwe chete.

Kunzwisisa nzira dzekushanda uye mutsauko we duplexers, triplexers, uye quadplexers kwakakosha pakugadzira nekugadzirisa masisitimu ekutaurirana asina waya. Kusarudza mhando yakakodzera ye multiplexer kunogona kuvandudza mashandisirwo e spectrum yesisitimu uye mhando yekutaurirana.
