Kusanthula mozama kwa mfundo zogwirira ntchito ndi kugwiritsa ntchito ma duplexers, ma triplexers ndi quadplexers

M'makina amakono olumikizirana opanda zingwe, ma duplexers, ma triplexers ndi ma quadplexer ndi zinthu zofunika kwambiri kuti mukwaniritse kufalitsa ma siginecha amitundu yambiri. Amaphatikiza kapena kulekanitsa ma siginecha kuchokera kumagulu angapo pafupipafupi, kulola zida kutumiza ndikulandila ma frequency angapo nthawi imodzi ndikugawana tinyanga. Ngakhale kusiyana kwa mayina ndi mapangidwe, mfundo zawo zoyambira ndizofanana, kusiyana kwakukulu ndi chiwerengero ndi zovuta zamagulu afupipafupi opangidwa.

Duplexer

Duplexer imakhala ndi zosefera ziwiri zomwe zimagawana doko lofanana (nthawi zambiri mlongoti) ndipo amagwiritsidwa ntchito kukhazikitsa ntchito zotumizira (Tx) ndikulandila (Rx) pachida chomwecho. Amagwiritsidwa ntchito makamaka pamakina a frequency division duplex (FDD) kuti apewe kusokonezana polekanitsa ma transmit ndi kulandira ma sign. Ma Duplexers amafunikira kudzipatula kwakukulu, nthawi zambiri pamwamba pa 55 dB, kuwonetsetsa kuti siginecha yopatsirana sikhudza kukhudzika kwa wolandila.

Triplexer

Triplexer imakhala ndi zosefera zitatu zomwe zimagawana doko lofanana. Zimalola chipangizo kuti chizitha kugwiritsira ntchito zizindikiro kuchokera kumagulu atatu osiyanasiyana afupipafupi nthawi imodzi ndipo nthawi zambiri amagwiritsidwa ntchito muzitsulo zoyankhulirana zomwe zimafunika kuthandizira maulendo angapo nthawi imodzi. Mapangidwe a triplexer akuyenera kuwonetsetsa kuti passband ya fyuluta iliyonse siyikukweza zosefera zina ndikupereka kudzipatula kokwanira kuti apewe kusokoneza pakati pa ma frequency band.

Quadplexer

Quadplexer imakhala ndi zosefera zinayi zomwe zimagawana doko lofanana. Zimapangitsa kuti chipangizochi chizitha kugwiritsira ntchito zizindikiro kuchokera kumagulu anayi osiyana siyana panthawi imodzi ndipo ndizoyenera machitidwe oyankhulana ovuta omwe amafunikira luso lapamwamba la spectral, monga teknoloji ya carrier aggregation. Kuvuta kwa kapangidwe ka quadplexer ndikokwera kwambiri ndipo kumafunika kukwaniritsa zofunikira zodzipatula kuti zitsimikizire kuti ma siginecha pakati pa ma frequency sakusokonezana.

Kusiyana kwakukulu

Chiwerengero cha ma frequency band: Ma Duplexers amakonza ma frequency awiri, ma triplexers amakonza ma frequency atatu, ndipo ma quadplexers amakonza ma frequency anayi.

Kuvuta kwa mapangidwe: Pamene kuchuluka kwa ma frequency band kumachulukira, zovuta zamapangidwe ndi zofunikira zodzipatula zimakulanso molingana.

Zochitika zogwiritsira ntchito: Ma Duplexers amagwiritsidwa ntchito nthawi zambiri m'makina oyambira a FDD, pomwe ma triplex ndi ma quadplexers amagwiritsidwa ntchito pamakina olumikizirana apamwamba omwe amafunikira kuthandizira ma frequency angapo nthawi imodzi.

Kumvetsetsa mitundu yogwirira ntchito komanso kusiyana kwa ma duplexers, ma triplexers, ndi quadplexers ndikofunikira pakupanga ndi kukhathamiritsa makina olumikizirana opanda zingwe. Kusankha mtundu woyenera wa ma multiplexer kutha kupititsa patsogolo kagwiritsidwe ntchito ka makina komanso kulumikizana bwino.
