Qualcomm Technologies, kuwonjezera pa , idayambitsa ukadaulo wake wamakono wa ultraSAW RF wa zosefera za 4G/5G zam'manja. Imawongolera kwambiri magwiridwe antchito a wailesi mpaka 2,7 GHz ndipo, malinga ndi wopanga, imaposa omwe akupikisana nawo potengera magawo ndi mtengo.
Zosefera za mawayilesi (RF) zimalekanitsa ma siginecha a wailesi m'magulu osiyanasiyana omwe amagwiritsidwa ntchito m'mafoni a m'manja kuti alandire ndi kutumiza zidziwitso. Pochepetsa kutayika koyika ndi osachepera 1 dB, zosefera za Qualcomm ultraSAW surface acoustic wave (SAW) zimakhala zogwira mtima kwambiri kuposa zosefera zomwe zimapikisana ndi body acoustic wave (BAW) mpaka 2,7 GHz.
Qualcomm ultraSAW imakhala ndi kusefa kwakukulu mumtundu wa 600 MHz - 2,7 GHz ndi mawonekedwe:
- kulekanitsa bwino kwambiri kwa ma siginecha olandilidwa ndi opatsirana ndi kuponderezana kwa crosstalk;
- high frequency selectivity;
- zinthu zabwino mpaka 5000 - zapamwamba kwambiri kuposa zosefera za OAV zopikisana;
- kutayika kochepa kwambiri kolowetsa;
- Kukhazikika kwa kutentha kwakukulu ndi kutentha kochepa kwambiri kwa dongosolo la x10-6 / deg. KWA.
Ukadaulo umalola opanga kuwongolera mphamvu zamagetsi zamagetsi zamitundu yambiri ya 5G ndi 4G pomwe amachepetsa ndalama poyerekeza ndi mayankho ampikisano omwe ali ndi luso lofananira. Chifukwa cha kugwiritsa ntchito zipangizo zamakono, mafoni a m'manja adzagwira ntchito motalika, ndipo khalidwe la kulankhulana lidzakula. Kupanga kwa banja la Qualcomm ultraSAW lazinthu zophatikizika komanso zophatikizika zidzayamba mugawo lapano, ndipo zida zoyambira zoyambira pazidazi zidzawonekera theka lachiwiri la 2020.
Qualcomm ultraSAW ndiukadaulo wofunikira wopititsa patsogolo magwiridwe antchito amakampani a RFFE ndi Snapdragon 5G Modem-RF modem system. Ukadaulo wa Qualcomm ultraSAW umagwiritsidwa ntchito m'ma module amplifier power (PAMiD), ma module am front end (FEMiD), diversity modules (DRx), Wi-Fi extractors, navigation signal extractors (GNSS extractors), ndi RF multiplexers.
