Kusanthula mozama mfundo zogwirira ntchito ndi momwe ma duplexers, triplexers ndi quadplexers amagwirira ntchito

Mu machitidwe amakono olumikizirana opanda zingwe, ma duplexer, ma triplexer ndi ma quadplexer ndi zinthu zofunika kwambiri kuti zitheke kutumiza ma signal a multi-band. Amaphatikiza kapena kulekanitsa ma signal kuchokera ku ma frequency band angapo, zomwe zimathandiza kuti zipangizo zitumize ndikulandira ma frequency band angapo nthawi imodzi pamene zikugawana ma antenna. Ngakhale kuti pali kusiyana kwa mayina ndi kapangidwe kake, mfundo zawo zazikulu ndizofanana, ndipo kusiyana kwakukulu ndi kuchuluka ndi zovuta za ma frequency band omwe amakonzedwa.

Duplexer

Duplexer imakhala ndi zosefera ziwiri zomwe zimagawana doko limodzi (nthawi zambiri antenna) ndipo zimagwiritsidwa ntchito kukhazikitsa ntchito za transmit (Tx) ndi receiver (Rx) pa chipangizo chimodzi. Imagwiritsidwa ntchito makamaka mu machitidwe a frequency division duplex (FDD) kuti apewe kusokonezana mwa kulekanitsa ma transmit ndi receiver signals. Duplexers amafunika kudzipatula kwakukulu, nthawi zambiri kupitirira 55 dB, kuti atsimikizire kuti chizindikiro chotumizidwacho sichikhudza kukhudzidwa kwa wolandila.

Triplexer

Triplexer imakhala ndi zosefera zitatu zomwe zimagawana doko limodzi. Imalola chipangizocho kukonza ma signali ochokera ku ma frequency band atatu osiyanasiyana nthawi imodzi ndipo nthawi zambiri imagwiritsidwa ntchito m'makina olumikizirana omwe amafunika kuthandizira ma frequency band angapo nthawi imodzi. Kapangidwe ka triplexer kamafunika kuonetsetsa kuti passband ya fyuluta iliyonse siikweza ma frequency ena ndikupereka padera lokwanira kuti lisasokoneze ma frequency band.

Quadplexer

Chida cha quadplexer chimakhala ndi zosefera zinayi zomwe zimagawana doko limodzi. Chimalola chipangizochi kukonza ma siginecha kuchokera ku ma frequency band anayi osiyanasiyana nthawi imodzi ndipo chimayenera kugwiritsa ntchito njira zovuta zolumikizirana zomwe zimafuna luso lapamwamba la spectral, monga ukadaulo wolumikizirana ndi carrier. Kuvuta kwa kapangidwe ka quadplexer ndi kwakukulu ndipo kuyenera kukwaniritsa zofunikira zokhazikika kuti zitsimikizire kuti ma siginecha pakati pa ma frequency band sakusokonezana.

Kusiyana kwakukulu

Chiwerengero cha ma frequency band: Ma Duplexer amayendetsa ma frequency band awiri, ma triplexer amayendetsa ma frequency band atatu, ndipo ma quadplexer amayendetsa ma frequency band anayi.

Kuvuta kwa kapangidwe: Pamene kuchuluka kwa ma frequency band kukuwonjezeka, zovuta za kapangidwe ndi zofunikira zodzipatula zimawonjezekanso moyenerera.

Zochitika Zogwiritsira Ntchito: Ma Duplexer nthawi zambiri amagwiritsidwa ntchito mu machitidwe oyambira a FDD, pomwe ma triplexer ndi ma quadplexer amagwiritsidwa ntchito mu machitidwe apamwamba olumikizirana omwe amafunika kuthandizira ma frequency band angapo nthawi imodzi.

Kumvetsetsa njira zogwirira ntchito ndi kusiyana kwa ma duplexer, triplexer, ndi quadplexer ndikofunikira kwambiri popanga ndikuwongolera njira zolumikizirana zopanda zingwe. Kusankha mtundu woyenera wa multiplexer kungathandize kwambiri kugwiritsa ntchito ma spectrum a dongosololi komanso khalidwe la kulumikizana.
