Kutheni izihluzi zeRF zisibaluleka ngakumbi?
Ukukhula ngokukhawuleza kwedatha ye-wireless kunye neenethiwekhi ze-4G LTE zikhokelele kwimfuno ekhulayo yamaqela amatsha kunye nokuhlanganiswa komthwali ukudibanisa iibhendi ukulungiselela ukuthuthwa kwamacingo. Inethiwekhi ye-3G isebenzisa kuphela malunga namaqela amahlanu, kwaye iinethiwekhi ze-LTE ngoku zisebenzisa ngaphezu kweebhendi ze-40, kwaye ngokufika kwe-5G, inani leebhendi liya kwanda ngakumbi.
Izixhobo eziqhagamshelweyo zithumela imiqondiso kwiibhendi ezininzi: iselula, iWi-Fi, iBluetooth, kunye neGPS, ngelixa uphepha ukuphazamiseka. Sinokucinga ngoko nangoko ngee-smartphones, amaphiko kashaka abekwe phezulu kwiimoto, izikhululo zesiseko seselula, iradar kunye neenkqubo zonxibelelwano, kunye neshishini, isayensi, okanye izicelo zonyango eziqhagamshelwe kwi-Intanethi yeZinto (IoT). Ngeli xesha, isihluzo siyafuneka ukuze siphume.
I-smartphone engenasihluzi sisitena
Njengee-eriyali, izihluzi ziya ziba yinxalenye ebalulekileyo yabaxube benethiwekhi. Isixhobo sifumana iifrikhwensi ezahlukeneyo, kwaye isihluzi sivumela ifrekhwensi efunwayo ukuba idlule ngelixa icinezela amaza angafunekiyo. Ngamanye amazwi, icebo lokucoca lifana neGandalf kuJohn Ronald Ryall Tolkien "INkosi yeeNdandatho": "Awuyi kudlula!" "Izixhobo zanamhlanje zihlala zixhotyiswe ngeefilitha ze-30 ukuya kwi-40 ukuphepha ukuphazamiseka. Le meko iya kuba nzima ngakumbi njengoko isizukulwana esilandelayo see-smartphones eziphezulu zifuna izihlungi ezininzi.
Imingeni yoyilo lwesihluzi
Izihluzi sisixhobo esibalulekileyo kwiinjineli zoyilo zeRF, kodwa zikwajongene nemingeni emininzi. Ukuqala, ukusebenza kwesihluzi kuyahluka kunye nobushushu. Izihluzi kwizixhobo ezahlukeneyo namhlanje zinokumelana nobushushu obuphakathi kwama-60 degrees celcius (140 degrees Fahrenheit) okanye ngaphezulu, ngelixa izihluzi zangaphakathi zinokumelana nobushushu obuphakathi kwama-25 degrees celcius (77 degrees Fahrenheit) kunye namaqondo obushushu aphezulu kumaphiko ookrebe okanye izihluzo ezifakwe ngaphakathi. uphahla. Ukuphakama kweqondo lobushushu lesihluzi, kokukhona kuya kuba nzima ukuhluza i-frequency ethile, kwaye ngakumbi kunokwenzeka ukuba umqondiso "uyakhukuliseka" kwibhendi ekufutshane.
Ukulawula ukukhukuliseka kobushushu kubaluleke kakhulu kuba uninzi lwamabhanti asanda kwabelwa asondele kakhulu kumabhanti akhoyo. Ngexesha elifanayo, i-carrier aggregation (CA) ikhula ngokukhawuleza, kunye nababoneleli ngenkonzo yeselula badibanisa ukuya kuthi ga kwi-five channels carrier ukuze baqinisekise ukusebenza kwenethiwekhi, apho ukucoca ngokuchanekileyo kuyimfuneko.
Ukujongana nemiba yobushushu, ishishini leRF liphuhlisa ubugcisa bokucoca obungakhukulilekiyo kunye nobungakhukulilekiyo. I-Sonic Sonic (SAW) kunye ne-Body Sound Wave (BAW) izihlungi zigcina iqondo eliphezulu lokuzinza xa ubushushu buguquka, ukuhlangabezana neemfuno ezifunekayo zokusebenza kwezixhobo ezivelayo.
Njengoko kukhankanyiwe ngasentla, isizukulwana esilandelayo see-smartphones eziphakamileyo nazo kufuneka zixhotyiswe ngeefilitha ezininzi. Njengawo onke amanye amalungu e-rf, kukho indawo encinci kakhulu yezihluzi. Iinjineli kufuneka zikwazi ukudibanisa izihluzi ezininzi kwiindawo ezincinci zokusebenza okuphezulu.
I-Duplexers, i-triplexers, i-cuadruplexers kunye ne-hexaplexer ngokudibeneyo zibizwa ngokuba zii-multiplexers. Ii-Multiplexers zidibanisa izihluzi ezininzi kwisixhobo esinye ukunceda abaqulunqi bonga indawo, ukwenza lula uyilo, ukuhlangabezana neemfuno zokusebenza, kunye nokunqanda ukuphazamiseka.
Kwiindawo eziphathwayo zanamhlanje, inani leebhendi ezifunekayo kwisixhobo liyamangalisa, kwaye ngokufika kwexesha le-5G, lo mkhwa uya kuba mbi ngakumbi. Ngelixa ukuxhasa zonke iibhendi kunokubangela iingxaki zokuphazamiseka, ingxaki inokusombulula ngesihluzo. Ngaphandle kwezihluzi, inethiwekhi ayisebenzi.

Ndiyathemba ukuba ungayifumana le nto uyikhangelayo, ukuba akunjalo, sikwabonelela ngokwenza umzobo wakho.
