RF kutsogolo-kumapeto gawo: mphamvu yoyendetsera nthawi ya 5G

RF front-end module (FEM) imagwira ntchito yofunika kwambiri pamayendedwe amakono opanda zingwe, makamaka mu nthawi ya 5G. Amapangidwa makamaka ndi zigawo zikuluzikulu monga mphamvu amplifier (PA),fyuluta,duplexer, RF switch ndiLow Noise amplifier (LNA)kuonetsetsa mphamvu, bata ndi khalidwe la chizindikiro.

Chokulitsa mphamvu ndichokulitsa chizindikiro cha RF, makamaka mu 5G, chomwe chimafuna kuchita bwino kwambiri komanso mzere wapamwamba. Zosefera zimasankha chizindikiro chafupipafupi kuti zisefe zizindikiro zosokoneza kuti zitsimikizire kuyera kwa kufalitsa ma siginecha. Mu band yapamwamba kwambiri, zosefera zamtundu wa acoustic wave (SAW) ndi bulk acoustic wave (BAW) zili ndi zabwino ndi zoyipa zawo. Zosefera za BAW zimagwira ntchito bwino pama frequency apamwamba, koma mtengo wake ndi wapamwamba.

Theduplexerimathandizira njira yolumikizirana ya ma frequency division duplex (FDD) kuti iwonetsetse kuti kulumikizana kwa njira ziwiri, pomwe RF switch ili ndi udindo wosinthira njira yama siginecha, makamaka m'malo amagulu angapo a 5G, omwe amafunikira kutayika pang'ono kuyika ndikusintha mwachangu. Theotsika phokoso amplifierzimatsimikizira kuti chizindikiro chofooka cholandilidwa sichikusokonezedwa ndi phokoso.

Ndi chitukuko cha teknoloji ya 5G, ma modules akutsogolo a RF akupita ku mgwirizano ndi miniaturization. Ukadaulo wapackage wa SiP umaphatikiza zigawo zingapo za RF palimodzi, kuwongolera kuphatikiza ndikuchepetsa mtengo. Nthawi yomweyo, kugwiritsa ntchito zida zatsopano monga liquid crystal polymer (LCP) ndi modified polyimide (MPI) m'munda wa antenna kumapititsa patsogolo mphamvu ya kufalitsa ma siginecha.

Kukonzekera kwa ma modules akutsogolo a RF kwalimbikitsa kupita patsogolo kwa mauthenga a 5G, ndipo kudzapitirizabe kuchitapo kanthu pa mauthenga opanda zingwe m'tsogolomu, kubweretsa mwayi wochuluka wa chitukuko cha zamakono.
