Ukuhlaziywa okujulile kwezimiso zokusebenza kanye nokusetshenziswa kwama-duplexer, ama-triplexer kanye nama-quadplexer

Ezinhlelweni zokuxhumana ezingenantambo zanamuhla, ama-duplexer, ama-triplexer nama-quadplexer ayizingxenye ezibalulekile ezingasebenzi ukuze kufezwe ukudluliswa kwesignali yama-multi-band. Ahlanganisa noma ahlukanise amasignali kuma-frequency band amaningi, avumela amadivayisi ukuthi adlulise futhi amukele ama-frequency band amaningi ngesikhathi esisodwa ngenkathi abelana ngama-antenna. Naphezu komehluko wamagama nezakhiwo, izimiso zawo eziyisisekelo ziyafana, umehluko omkhulu uyinani kanye nobunzima bama-frequency band acutshungulwayo.

I-Duplexer

I-duplexer inezihlungi ezimbili ezabelana ngembobo efanayo (ngokuvamile i-antenna) futhi ezisetshenziselwa ukusebenzisa imisebenzi yokudlulisa (Tx) nokwamukela (Rx) kudivayisi efanayo. Isetshenziswa kakhulu ezinhlelweni ze-duplex (FDD) zokuhlukanisa imvamisa ukuvimbela ukuphazamiseka okuhambisanayo ngokuhlukanisa izimpawu zokudlulisa nezokwamukela. Ama-duplexer adinga izinga eliphezulu lokuhlukaniswa, ngokuvamile ngaphezu kwama-55 dB, ukuqinisekisa ukuthi isignali edluliselwe ayithinti ukuzwela komamukeli.

I-Triplexer

I-tripplexer inezihlungi ezintathu ezabelana nge-port efanayo. Ivumela idivayisi ukuthi icubungule amasignali avela kuma-frequency band amathathu ahlukene ngesikhathi esisodwa futhi ivame ukusetshenziswa ezinhlelweni zokuxhumana ezidinga ukusekela ama-frequency band amaningi ngesikhathi esisodwa. Umklamo we-tripplexer udinga ukuqinisekisa ukuthi i-passband yesihlungi ngasinye ayilayishi ezinye izihlungi futhi inikeze ukuhlukaniswa okwanele ukuvimbela ukuphazamiseka okuhlangene phakathi kwama-frequency band.

I-Quadplexer

I-quadplexer inezihlungi ezine ezihlanganyela i-port efanayo. Ivumela idivayisi ukuthi icubungule amasignali avela kuma-frequency band amane ahlukene ngesikhathi esisodwa futhi ifanele izinhlelo zokuxhumana eziyinkimbinkimbi ezidinga ukusebenza kahle okuphezulu kwe-spectral, njengobuchwepheshe bokuhlanganisa abathwali. Ubunzima bokuklama kwe-quadplexer buphakeme kakhulu futhi kudinga ukuhlangabezana nezidingo eziqinile zokuhlukaniswa ukuze kuqinisekiswe ukuthi amasignali aphakathi kwama-frequency band awaphazamisi omunye nomunye.

Umehluko omkhulu

Inani lama-frequency band: Ama-Duplexer acubungula ama-frequency band amabili, ama-triplexer acubungula ama-frequency band amathathu, kanti ama-quadplexer acubungula ama-frequency band amane.

Ubunzima bomklamo: Njengoba inani lamabhendi emvamisa landa, ubunzima bomklamo kanye nezidingo zokuhlukaniswa nazo ziyanda ngokufanele.

Izimo Zokusebenza: Ama-Duplexer avame ukusetshenziswa ezinhlelweni eziyisisekelo ze-FDD, kuyilapho ama-triplexer nama-quadplexer esetshenziswa ezinhlelweni zokuxhumana ezithuthukisiwe ezidinga ukusekela ama-frequency band amaningi ngesikhathi esisodwa.

Ukuqonda izindlela zokusebenza kanye nomehluko wama-duplexer, ama-triplexer, nama-quadplexer kubalulekile ekuklameni nasekuthuthukiseni izinhlelo zokuxhumana ezingenantambo. Ukukhetha uhlobo lwe-multiplexer olufanele kungathuthukisa ngempumelelo ukusetshenziswa kwe-spectrum yesistimu kanye nekhwalithi yokuxhumana.
