Uhlalutyo olunzulu lwemigaqo yokusebenza kunye nokusetyenziswa kwe-duplexers, i-triplexers kunye ne-quadplexers

Kwiinkqubo zonxibelelwano ezingenazingcingo zanamhlanje, ii-duplexers, ii-triplexers kunye nee-quadplexers ngamacandelo aphambili angenzi nto ukuze kuphunyezwe ukuhanjiswa komqondiso wamaqela amaninzi. Badibanisa okanye bahlula imiqondiso kwiibhendi zamaza amaninzi, ezivumela izixhobo ukuba zisasaze kwaye zifumane iibhendi zamaza amaninzi ngaxeshanye ngelixa sabelane ngee-eriyali. Ngaphandle kokwahluka kwamagama kunye nezakhiwo, imigaqo yazo esisiseko iyafana, kunye nowona mahluko ophambili inani kunye nobunzima beebhendi zefrikhwensi ezicutshungulwayo.

Duplexer

I-duplexer inezihluzo ezimbini ezabelana ngezibuko eziqhelekileyo (ezidla ngokuba yi-eriyali) kwaye zisetyenziselwa ukuphumeza imisebenzi yokudlulisa (Tx) kunye nokwamkela (Rx) kwisixhobo esinye. Isetyenziswa ikakhulu kwiinkqubo ze-frequency division duplex (FDD) ukuthintela ukuphazamisana ngokwahlula ukuhambisa kunye nokufumana imiqondiso. I-Duplexers idinga izinga eliphezulu lokuzihlukanisa, ngokuqhelekileyo ngaphezu kwe-55 dB, ukuqinisekisa ukuba isignali edlulisiweyo ayichaphazeli uvakalelo lommkeli.

I-Triplexer

I-triplexer inezihluzo ezithathu ezabelana ngezibuko eliqhelekileyo. Ivumela isixhobo ukuba sisebenze imiqondiso evela kwiibhendi ezintathu ezahlukeneyo zefrikhwensi ngaxeshanye kwaye isoloko isetyenziswa kwiinkqubo zonxibelelwano ezifuna ukuxhasa iibhendi zamaza amaninzi ngaxeshanye. Uyilo lwetriplexer kufuneka luqinisekise ukuba ipasband yesihluzi ngasinye ayilayishi ezinye izihluzi kwaye ibonelele ngokwahlula okwaneleyo ukuthintela uphazamiseko phakathi kweebhendi zamaza.

Quadplexer

I-quadplexer inezihluzo ezine ezabelana ngezibuko eliqhelekileyo. Ivumela ifowuni ukuba isebenze imiqondiso evela kwiibhendi zamaza ohlukeneyo ezine ngaxeshanye kwaye ifanelekile kwiisistim zonxibelelwano ezintsonkothileyo ezifuna ukusebenza kakuhle kokubonwayo, okufana netekhnoloji ye-carrier aggregation. Ubunzima boyilo lwe-quadplexer luphezulu kwaye kufuneka luhlangabezane neemfuno ezingqongqo zokuzihlukanisa ukuze kuqinisekiswe ukuba imiqondiso phakathi kweebhendi zefrikhwensi ayiphazamisi omnye komnye.

Umahluko ophambili

Inani leebhendi zefrikhwensi: IiDuplexers zenza iibhendi zamaza ezibini, ii-triplexers ziqhuba iibhendi zamaza ezithathu, kunye ne-quadplexers zenza iibhendi ezine zamaza.

Ubunzima boyilo: Njengoko inani leebhendi zefrikhwensi lisanda, ubunzima boyilo kunye neemfuno zokuzihlukanisa nazo zonyuka ngokufanelekileyo.

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

Ukuqonda iindlela zokusebenza kunye nomahluko wee-duplexers, ii-triplexers, kunye ne-quadplexers kubalulekile ekuyileni nasekuphuculeni iinkqubo zonxibelelwano ezingenazingcingo. Ukukhetha uhlobo olufanelekileyo lwe-multiplexer kunokuphucula ngokufanelekileyo ukusetyenziswa kwenkqubo ye-spectrum kunye nomgangatho wonxibelelwano.
