I-Qualcomm Technologies, ngaphezu kwalokho , yethule ubuchwepheshe bayo bokuhlunga be-ultraSAW RF obusha kumadivayisi eselula e-4G/5G. Ithuthukisa kakhulu ukusebenza kwefrikhwensi yomsakazo kumabanga afika ku-2,7 GHz futhi, ngokomkhiqizi, iphakeme kuneqhudelana naye ngokwemigomo nezindleko.
Izihlungi zefrikhwensi yomsakazo (RF) zihlukanisa amasignali omsakazo kumabhendi ahlukahlukene asetshenziswa kumaselula ukwamukela nokudlulisa ulwazi. Ngokunciphisa ukulahlekelwa kokufaka okungenani ngo-1 dB, izihlungi ze-Qualcomm ultraSAW surface acoustic wave (SAW) zidlula izihlungi ezincintisanayo ze-acoustic wave (BAW) ezifika ku-2,7 GHz.
I-Qualcomm ultraSAW ifaka ukusebenza kokuhlunga okuphezulu ebangeni le-600 MHz - 2,7 GHz, futhi ibonakala ngezinzuzo ezilandelayo:
- ukuhlukaniswa okuhle kakhulu kwezimpawu ezitholiwe nezidlulisiwe kanye nokucindezelwa kwe-crosstalk;
- high frequency selectivity;
- isici sekhwalithi esifika ku-5000 - siphakeme kakhulu kunaleso sezihlungi ze-OAV ezincintisanayo;
- ukulahlekelwa okuncane kakhulu kokufaka;
- izinga lokushisa eliphezulu eliqinile ngokukhukhuleka kwezinga lokushisa eliphansi kakhulu lokuhleleka kwe-x10-6/deg. KUYA.
Ubuchwepheshe buvumela abakhiqizi ukuthi bathuthukise ukusebenza kahle kwamandla kwamadivayisi we-multi-mode 5G kanye ne-4G ngenkathi behlisa izindleko uma kuqhathaniswa nezixazululo zokuncintisana ezinezici ezifanayo zobuchwepheshe. Ngenxa yokusetshenziswa kobuchwepheshe, ama-smartphone azosebenza ngokuzenzakalelayo isikhathi eside, futhi izinga lokuxhumana lizokhula. Ukukhiqizwa komndeni wakwa-Qualcomm ultraSAW wemikhiqizo ehlukahlukene nehlanganisiwe kuzoqala kwikota yamanje, futhi imishini yokuqala ephambili esekelwe kuyo izovela engxenyeni yesibili ka-2020.
I-Qualcomm ultraSAW iwubuchwepheshe obubalulekile bokuqhubeka nokuthuthukisa ukusebenza kwephothifoliyo yenkampani ye-RFFE kanye nezinhlelo zemodemu ye-Snapdragon 5G yeModemu-RF. Ubuchwepheshe be-Qualcomm ultraSAW busetshenziswa kumamojula we-amplifier yamandla (PAMiD), amamojula angaphambili (FEMiD), amamojula ahlukene (DRx), ama-Wi-Fi extractors, ama-extractor signal navigation (GNSS extractors), kanye nama-multiplexers e-RF.
