Namuhla, ngokuthuthuka okwandayo kobuchwepheshe bezokuxhumana ngeselula, i-PCB) Ibhodi Yesifunda (PCB) ngaphakathi kwama-Smartphones selibaluleke kakhulu, libe yimithombo ebalulekile yesibili kuphela ku-Radio Spectrum.Ukubhekana nesidingo esikhulayo samabhande imvamisa yomsakazo, indawo ye-PCB yama-Smartphones ibhekana nezinselelo ezinkulu.Lezi zinselelo zivela ekukhuphukeni kwezakhiwo zomsakazo (RF) ezingaphambili, kufaka phakathi ukushintshwa kwamandla, ukushintshwa kwamabhendi amaningi, njll. Ngasikhathi sinye, isidingo sezikrini ezinamandla ngokwengeziwe, amaprosesa anamandla okwenziwaKunzima kakhulu ukwandisa ngokuphumelelayo kokuphela kwe-RF endaweni ekhawulelwe.
Ngokumelene nalesi sizinda, i-Qualcomm Technologies Inc. (QTI) yethule i-Qualcomm RF360 Radio Frency Freence Front-End Solution, okuyindlela ehlanganiswe kakhulu ehlanganisa izingxenye ezahlukahlukene eziyisisekelo phakathi kwemodemu ne-antenna.Ngokuhlanganisa ukushintshwa kwe-antenna, ama-amplifiers e-RF, njll.Ngaphezu kwalokho, lesi sixazululo singanciphisa futhi usayizi wokuqamba we-SKU eyodwa futhi wandise izinzuzo zesilinganiso sokukhiqiza.Njengoba ikhambi likhishwe ngoFebhuwari kulo nyaka, abakhiqizi abaningi be-OEM sebeqalile ukuba bamukele futhi kulindeleke ukuthi bakha imikhiqizo ehambisanayo ngaphambi kokuphela konyaka.Lesi sixazululo senzelwe ngombono wezinga lesistimu kusuka ezigabeni zokuqala futhi singasebenza ngokubambisana nezingxenye ezahlukahlukene zehadiwe ze-terminal ukuhlinzeka ngentuthuko entsha yokusebenza.
Ezingeni lobuchwepheshe, le ndlela yokuklama isuselwa ekunwetsheni okuqhubekayo kwamanethiwekhi we-Global 2G kanye nama-3G, futhi ikakhulukazi isetshenziselwa ukuxazulula inkinga yamabhendi wemvamisa ongewona umfaniswano obangelwa yi-4G LTE (FDD ne-TDD).Lo mklamo wangaphambili ungasekela wonke ama-band afrikhwensi afanele esigungwini esisodwa noma ama-skus ambalwa ngangokunokwenzeka ngaphandle kokukhulisa izidingo zesikhala noma ukusebenza okunomthelela.
Ezingeni lezomnotho, lo mklamo wokuqala we-Front-End usiza abakhiqizi be-terminal balekela ukukhiqizwa futhi banciphise kakhulu izindleko.Esikhundleni sokudinga imiklamo ehlukene eyi-10 ukufeza izidingo ze-Global LTE Band, ama-OEMS manje angasebenzisa amadizayini amathathu noma ambalwa ngaphandle kokushintsha ukwakheka kwebhodi noma indawo ekhuphukayo yebhodi.
Ekugcineni, inselelo enkulu kwinkambu ye-RF yindlela yokubhekana nokukhula okusheshayo kwesidingo senkonzo kanye namandla enethiwekhi ngaphandle kokukhuphula isikhala se-PCB.Njengamanje, inani eliphelele lamabhande avalemele amaselula emhlabeni lifinyelele kuma-40, futhi abakhiqizi be-OEM badinga ukwethula izikhungo ezahlukahlukene eziphathwayo ukufeza ukubuyiselwa okuphezulu kokutshalwa kwemali komkhiqizo.Izisombululo ze-RF zendabuko zinokulinganiselwa ekubhekaneni nalezi zinselelo, futhi lesi sixazululo esisha kusuka ku-Qualcomm sinikeza amathuba amasha abakhiqizi be-mobile esibulalayo, abavumele bafeze ukumbozwa okubanzi ezindaweni ezilinganiselwe.
