Qualcomm Technologies, ho phaella ho , e hlahisitse theknoloji ea eona e ncha ea ultraSAW RF filter bakeng sa lisebelisoa tsa mohala tsa 4G/5G. E ntlafatsa haholo ts'ebetso ea maqhubu a seea-le-moea ho fihla ho 2,7 GHz 'me, ho ea ka moetsi, e phahametse bahlolisani ho latela litekanyetso le litšenyehelo.
Lisefe tsa radio frequency (RF) li arola mats'oao a seea-le-moea ka har'a lihlopha tse fapaneng tse sebelisoang mehalang ea cellular ho amohela le ho fetisa tlhahisoleseling. Ka ho fokotsa tahlehelo ea ho kenya bonyane 1 dB, li-filters tsa Qualcomm ultraSAW surface acoustic wave (SAW) li feta lihlopha tse hlōlisanang tsa 'mele oa acoustic wave (BAW) ho fihla ho 2,7 GHz.
Qualcomm ultraSAW e fana ka ts'ebetso e phahameng ea ho sefa sebakeng sa 600 MHz - 2,7 GHz, 'me e tšoauoa ka melemo e latelang:
- karohano e ntle haholo ea matšoao a amoheloang le a fetisoang le khatello ea crosstalk;
- high frequency selectivity;
- ntlha ea boleng ho fihla ho 5000 - e phahame haholo ho feta ea litlholisano tsa OAV tse hlolisang;
- tahlehelo e tlase haholo ea ho kenya;
- botsitso bo phahameng ba mocheso le mocheso o tlase haholo oa taelo ea x10-6/deg. TSA.
Theknoloji e lumella bahlahisi ho ntlafatsa matla a matla a lisebelisoa tse ngata tsa 5G le 4G ha ba ntse ba fokotsa litšenyehelo ha ba bapisoa le litharollo tsa tlhōlisano tse nang le litšobotsi tse tšoanang tsa theknoloji. Ka lebaka la ts'ebeliso ea thekenoloji, li-smartphone li tla sebetsa ka nako e telele, 'me boleng ba puisano bo tla eketseha. Tlhahiso ea lelapa la Qualcomm ultraSAW ea lihlahisoa tse sa tšoaneng le tse kopantsoeng li tla qala kotareng ea hona joale, 'me lisebelisoa tsa pele tse thehiloeng ho eona li tla hlaha halofo ea bobeli ea 2020.
Qualcomm ultraSAW ke theknoloji ea bohlokoa ho ntlafatsa ts'ebetso ea potefolio ea k'hamphani ea RFFE le litsamaiso tsa modem tsa Snapdragon 5G Modem-RF. Theknoloji ea Qualcomm ultraSAW e sebelisoa ho li-module tsa amplifier ea matla (PAMiD), li-modules tse ka pele (FEMiD), li-diversity modules (DRx), li-extractors tsa Wi-Fi, li-extractors tsa navigation signal (GNSS extractors), le RF multiplexers.
