Qualcomm Technologies, kuwedzera kune , yakaunza hunyanzvi hwayo hweUltraSAW RF sefa ye4G/5G nharembozha. Iyo inovandudza zvakanyanya redhiyo frequency kuita mumarenji anosvika 2,7 GHz uye, sekureva kwemugadziri, inokwirisa kune vanokwikwidza maererano nemaparamita uye mutengo.
Mafirita eredhiyo (RF) anoparadzanisa masaini eredhiyo mumabhendi akasiyana-siyana anoshandiswa munharembozha kugamuchira uye kutumira ruzivo. Nekudzikisa kurasikirwa kwekuisa neinenge 1 dB, Qualcomm ultraSAW pamusoro acoustic wave (SAW) mafirita anopfuura anokwikwidza muviri acoustic wave (BAW) mafirita anosvika 2,7 GHz.
Qualcomm UltraSAW inoratidzira yakakwira kusefa kuita mu600 MHz - 2,7 GHz renji, uye inoratidzwa neanotevera mabhenefiti:
- kupatsanurwa kwakanaka kwazvo kwekugamuchira uye kutumirwa masaini uye crosstalk kudzvinyirira;
- high frequency selectivity;
- quality factor inosvika 5000 - yakanyanya kukwirira kupfuura iyo yekukwikwidza OAV mafirita;
- kurasikirwa kwakanyanya kwekuisa;
- kugadzikana kwekushisa kwakanyanya nekuderera kwakanyanya kwekushisa kweiyo x10-6 / deg. TO.
Iyo tekinoroji inobvumira vagadziri kuti vavandudze kushanda kwesimba kweakawanda-modhi 5G uye 4G zvishandiso uku vachidzikisa mutengo uchienzaniswa nemakwikwi mhinduro ane akafanana hunyanzvi hunhu. Nekuda kwekushandiswa kwetekinoroji, mafoni achashanda akazvimirira kwenguva refu, uye kunaka kwekutaurirana kuchawedzera. Kugadzirwa kweiyo Qualcomm ultraSAW mhuri ye discrete uye yakasanganiswa zvigadzirwa ichatanga muchikamu chazvino, uye yekutanga mureza michina yakavakirwa pairi ichaonekwa muhafu yechipiri ye2020.
Qualcomm UltraSAW tekinoroji yakakosha yekuwedzera mashandiro ekambani RFFE portfolio uye Snapdragon 5G Modem-RF modem masisitimu. Qualcomm ultraSAW tekinoroji inoshandiswa mumagetsi amplifier modules (PAMiD), front end modules (FEMiD), diversity modules (DRx), Wi-Fi extractors, navigation signal extractors (GNSS extractors), uye RF multiplexers.
