RF front-end module: simba guru rekutyaira renguva ye5G

RF front-end module (FEM) inoita basa rakakosha mukutaurirana kwemazuva ano kusina waya, kunyanya munguva ye5G. Inonyanya kuumbwa nezvinhu zvakakosha zvakaita sepower amplifier (PA),sefa,duplexer, RF switch uyeamplifier yeruzha rwakaderera (LNA)kuona kuti chiratidzo chacho chakasimba, chakagadzikana uye chine mhando.

Simba remagetsi rinoita kuti chiratidzo cheRF chiwedzere, kunyanya mu5G, izvo zvinoda kushanda zvakanaka uye kurongeka kwakanyanya. Sefa iyi inosarudza chiratidzo chefrequency chaiyo kuti isefe zviratidzo zvekupindira kuti ive nechokwadi chekuchena kwekutumira kwesignali. Mubhendi refrequency yepamusoro, mafirita esurface acoustic wave (SAW) uye bulk acoustic wave (BAW) ane zvakanakira nezvaakaipira. Mafirita eBAW anoshanda zvirinani mubhendi refrequency yepamusoro, asi mutengo wacho wakakwira.

Iyoduplexerinotsigira sisitimu yekutaurirana yeFDD (frequency division duplex) kuti ive nechokwadi chekuti kutaurirana kwenzira mbiri kunoshanda, ukuwo switch yeRF ichibatsira pakuchinja nzira yesignal, kunyanya munzvimbo ine mabhendi akawanda e5G, iyo inoda kurasikirwa kwakaderera uye kuchinja nekukurumidza.amplifier ine ruzha rwakadererainoita kuti chiratidzo chisina simba chinogamuchirwa chisakanganiswa neruzha.

Nekuvandudzwa kwetekinoroji ye5G, mamodule eRF ari kufambira mberi pakubatanidzwa uye miniaturization. Tekinoroji yekurongedza yeSiP inosanganisa zvikamu zvakawanda zveRF pamwe chete, zvichivandudza kubatanidzwa uye zvichideredza mitengo. Panguva imwe chete, kushandiswa kwezvinhu zvitsva zvakaita se liquid crystal polymer (LCP) uye modified polyimide (MPI) mumunda weantenna zvinowedzera kuvandudza kushanda kwekutumira masaini.

Kuvandudzwa kwemaRF front-end modules kwakasimudzira kufambira mberi kwekutaurirana kwe5G, uye kucharamba kuchiita basa guru mukutaurirana kusina waya mune ramangwana, zvichiunza mikana yakawanda yekuvandudza tekinoroji.
