Uhlalutyo olunzulu lwemigaqo yokusebenza kunye nokusetyenziswa kwee-duplexers, ii-triplexers kunye nee-quadplexers

Kwiinkqubo zonxibelelwano ezingenazingcingo zanamhlanje, ii-duplexers, ii-triplexers kunye nee-quadplexers zizinto ezibalulekileyo ezingasebenziyo ukuze kufezekiswe ukuhanjiswa kwesignali ye-multi-band. Zidibanisa okanye zahlule imiqondiso kwiibhendi ezininzi ze-frequency, zivumela izixhobo ukuba zidlulise kwaye zithole iibhendi ezininzi ze-frequency ngaxeshanye ngelixa zabelana ngee-antenna. Nangona kukho umahluko kumagama kunye nezakhiwo, imigaqo yazo esisiseko iyafana, umahluko ophambili linani kunye nobunzima beebhendi ze-frequency ezicutshungulwayo.

I-Duplexer

I-duplexer inezihluzo ezimbini ezabelana ngezibuko elifanayo (ngesiqhelo i-antenna) kwaye zisetyenziselwa ukuphumeza imisebenzi yokudlulisa (Tx) kunye nokwamkela (Rx) kwisixhobo esinye. Isetyenziswa kakhulu kwiinkqubo ze-duplex (FDD) zokwahlulahlula i-frequency ukuthintela ukuphazamiseka okudibeneyo ngokwahlula imiqondiso yokudlulisa kunye nokufumana. I-duplexers ifuna inqanaba eliphezulu lokuzihlukanisa, ngesiqhelo ngaphezulu kwe-55 dB, ukuqinisekisa ukuba isignali edluliselweyo ayichaphazeli ubuntununtunu bomamkeli.

I-Triplexer

I-tripplexer inezihluzo ezintathu ezabelana ngezibuko elifanayo. Ivumela isixhobo ukuba sicubungule imiqondiso evela kwiibhendi ezintathu ezahlukeneyo zefrikhwensi ngaxeshanye kwaye idla ngokusetyenziswa kwiinkqubo zonxibelelwano ezifuna ukuxhasa iibhendi ezininzi zefrikhwensi ngaxeshanye. Uyilo lwe-tripplexer kufuneka luqinisekise ukuba i-passband yesihluzo ngasinye ayilayishi ezinye izihluzo kwaye ibonelele ngokwahlukileyo ukuthintela ukuphazamiseka okulinganayo phakathi kweebhendi zefrikhwensi.

I-Quadplexer

I-quadplexer inezihluzo ezine ezabelana ngezibuko elifanayo. Ivumela isixhobo ukuba sicubungule imiqondiso evela kwiibhendi ezine ezahlukeneyo zefrikhwensi ngaxeshanye kwaye ifanelekile kwiinkqubo zonxibelelwano ezintsonkothileyo ezifuna ukusebenza kakuhle kwe-spectral, njengetekhnoloji yokuhlanganisa abathwali. Ubunzima boyilo lwe-quadplexer buphezulu kwaye kufuneka buhlangabezane neemfuno ezingqongqo zokwahlulwa ukuze kuqinisekiswe ukuba imiqondiso phakathi kweebhendi zefrikhwensi ayiphazamisani.

Umahluko ophambili

Inani leebhendi zefrikhwensi: IiDuplexers zicubungula iibhendi ezimbini zefrikhwensi, iitriplexers zicubungula iibhendi ezintathu zefrikhwensi, kwaye iiquadplexers zicubungula iibhendi ezine zefrikhwensi.

Ubunzima boyilo: Njengoko inani leebhendi zefrikhwensi lisanda, ubunzima boyilo kunye neemfuno zokwahlulwa nazo ziyanda ngokufanelekileyo.

Iimeko zokusetyenziswa: Ii-Duplexers zihlala zisetyenziswa kwiinkqubo ze-FDD ezisisiseko, ngelixa ii-triplexers kunye nee-quadplexers zisetyenziswa kwiinkqubo zonxibelelwano eziphambili ezifuna ukuxhasa iibhendi ezininzi zamaza ngaxeshanye.

Ukuqonda iindlela zokusebenza kunye nomahluko phakathi kwee-duplexers, ii-triplexers, kunye nee-quadplexers kubalulekile ekuyileni nasekuphuculeni iinkqubo zonxibelelwano ezingenazingcingo. Ukukhetha uhlobo olufanelekileyo lwe-multiplexer kunokuphucula ngempumelelo ukusetyenziswa kwe-spectrum yenkqubo kunye nomgangatho wonxibelelwano.
