Impera ya RF ni iki?

1） RF imbere-impera nigice cyibanze cya sisitemu yitumanaho

Imbere ya radio yumurongo wimbere ifite umurimo wo kwakira no kohereza ibimenyetso bya radio yumurongo. Imikorere nubuziranenge nibyo bintu byingenzi bigena imbaraga zerekana ibimenyetso, umuvuduko wumuyoboro, umuvuduko wumurongo, ubwiza bwitumanaho, nibindi bipimo byitumanaho.

Mubisanzwe, ibice byose biri hagati ya antenne na transceiver ya RF hamwe hamwe byitwa RF imbere-impera. Modul ya RF-modules ihagarariwe na Wi-Fi, Bluetooth, selile, NFC, GPS, nibindi birashobora kumenya imiyoboro, ihererekanyabubasha rya dosiye, itumanaho, ikarita yohanagura, umwanya, nibindi bikorwa.

2） Gutondekanya no kugabana imikorere ya RF imbere-impera

Hariho ubwoko butandukanye bwa RF imbere-impera. Ukurikije ifishi, barashobora kugabanywamo ibikoresho byihariye na modul ya RF. Noneho, ibikoresho byihariye birashobora kugabanywamo ibice bitandukanye bikora ukurikije imikorere yabyo, kandi modul ya RF irashobora kugabanywa muburyo buke, buciriritse, hamwe nuburyo bwo kwishyira hamwe ukurikije urwego rwo kwishyira hamwe. itsinda. Mubyongeyeho, ukurikije inzira yo kohereza ibimenyetso, RF imbere-impera irashobora kugabanywamo inzira yohereza n'inzira yakira.

Kuva kugabana imikorere yibikoresho byihariye, igabanijwemo cyane imbaraga zongera imbaraga (PA),duplexer (Duplexer na Diplexer), radiyo yumurongo wa radiyo (Hindura),Akayunguruzo (Akayunguruzo)n'amajwi make amplifier (LNA), nibindi, wongeyeho chip ya baseband ikora sisitemu yuzuye ya radio yumurongo.

Imbaraga zongera imbaraga (PA) zishobora kongera ibimenyetso bya radiyo yumurongo wogukwirakwiza, kandi duplexer (Duplexer na Diplexer) irashobora gutandukanya ibimenyetso byohereza no kwakira kugirango ibikoresho bisangiye antenne imwe bishobora gukora bisanzwe; umurongo wa radiyo yumurongo (Hindura) urashobora kumenya radio yakira ibimenyetso byakira no guhererekanya guhinduranya, guhinduranya imirongo itandukanye; Akayunguruzo gashobora kugumana ibimenyetso mumirongo yihariye kandi ikungurura ibimenyetso hanze yumurongo wihariye; Urusaku ruke rwinshi (LNA) rushobora kongera ibimenyetso bito munzira yo kwakira.

Mugabanye hasi, iringaniye, kandi murwego rwo hejuru rwo guhuza ukurikije urwego rwo guhuza radio yumurongo wa radiyo. Muri byo, module hamwe no kwishyira hamwe kwinshi harimo ASM, FEM, nibindi, hamwe na module hamwe no guhuza hagati harimo Div FEM, FEMID, PAiD, SMMB PA, MMMB PA, RX Module, na TX Module, nibindi, module ifite urwego rwo hejuru rwa kwishyira hamwe harimo PAMiD na LNA Div FEM.

Inzira yohereza ibimenyetso irashobora kugabanwa munzira yohereza n'inzira yakira. Inzira yohereza ikubiyemo cyane cyane imbaraga zongera imbaraga hamwe nayunguruzo, kandi inzira yakira ikubiyemo cyane cyane imirongo ya radiyo ihinduranya amajwi, ibyuma byongera urusaku ruke, hamwe na filteri.
