Hauv kev sib txuas lus niaj hnub no, Xov Tooj Cua Frequency (RF) pem hauv ntej-kawg plays lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev sib txuas lus zoo wireless. Nyob nruab nrab ntawm tus kav hlau txais xov thiab digital baseband, RF pem hauv ntej-kawg yog lub luag haujlwm rau kev ua cov khoom xa tuaj thiab tawm, ua rau nws yog ib qho tseem ceeb hauv cov khoom siv xws li smartphones mus rau satellites.
RF Front-End yog dab tsi?
RF pem hauv ntej-kawg muaj ntau yam khoom siv uas tswj cov teeb liab txais thiab xa mus. Cov ntsiab lus tseem ceeb suav nrog lub hwj chim amplifiers (PA), lub suab nrov qis (LNA), cov ntxaij lim dej, thiab cov keyboards. Cov khoom no ua haujlwm ua ke los xyuas kom meej tias cov teeb liab kis tau nrog lub zog xav tau thiab pom tseeb, thaum txo kev cuam tshuam thiab suab nrov.
Feem ntau, tag nrho cov khoom nruab nrab ntawm tus kav hlau txais xov thiab RF transceiver raug xa mus rau RF pem hauv ntej-kawg, kom ntseeg tau tias cov teeb liab kis tau zoo.
2) Kev faib tawm thiab Kev Ua Haujlwm ntawm RF Front-End
RF pem hauv ntej-kawg tuaj yeem muab faib ua ob hom loj raws li nws raws li daim ntawv: cov khoom sib cais thiab RF modules. Cov khoom sib cais tau muab cais ntxiv raws li lawv txoj haujlwm, thaum RF modules tau muab faib ua qib qis, nruab nrab, thiab siab ua ke. Tsis tas li ntawd, nyob ntawm cov teeb liab kis tau tus mob, RF pem hauv ntej-kawg tau muab faib ua kev sib kis thiab kev txais tos.
Los ntawm kev faib ua haujlwm ntawm cov khoom siv sib cais, cov khoom tseem ceeb ntawm RF pem hauv ntej-kawg suav nrog rau hauv lub zog amplifier (PA), duplexer (Duplexer thiab Diplexer), xov tooj cua zaus hloov (Hloov), lim (Filter) thiab suab nrov nrov amplifier (LNA), lwm.,. Cov khoom siv no, ua ke nrog cov chips baseband, tsim kom tiav RF system.
Fais fab Amplifiers (PA): Txhim kho cov teeb liab raug xa mus.
Duplexers: Sib cais kis tau tus mob thiab txais cov cim, tso cai rau cov khoom siv sib koom tib lub kav hlau txais xov zoo.
Xov tooj cua zaus hloov (Hloov): Ua kom hloov pauv ntawm kev sib kis thiab kev txais tos lossis ntawm ntau zaus sib txawv.
Lim: Lim tawm cov zaus tsis xav tau thiab khaws cov teeb liab xav tau.
Low-Noise Amplifiers (LNA): Ua kom pom cov cim tsis muaj zog hauv txoj kev tau txais.
RF modules, raws li lawv cov qib kev sib koom ua ke, ntau yam los ntawm kev sib koom ua ke qis (xws li ASM, FEM) mus rau nruab nrab-kev sib koom ua ke modules (xws li Div FEM, FEMID, PAiD), thiab high-integration modules (xws li PAMiD, LNA Div FEM). ). Txhua hom module yog tsim los ua kom tau raws li kev thov sib txawv.
Qhov tseem ceeb hauv Kev Sib Txuas Lus
RF pem hauv ntej-kawg yog qhov tseem ceeb ntawm kev sib txuas lus wireless. Nws txiav txim siab qhov kev ua tau zoo tag nrho ntawm cov teeb liab lub zog, zoo, thiab bandwidth. Hauv cov xov tooj ntawm tes, piv txwv li, RF pem hauv ntej-kawg ua kom muaj kev sib txuas lus meej ntawm lub cuab yeej thiab lub hauv paus chaw nres tsheb, cuam tshuam ncaj qha rau kev hu xov tooj zoo, cov ntaub ntawv ceev, thiab kev pab them nqi ntau.
Kev cai RF Front-End Solutions
Apex tshwj xeeb hauv kev tsim cov khoom siv RF pem hauv ntej-kawg, muab cov kev daws teeb meem kom ua tau raws li cov kev cai tshwj xeeb ntawm kev sib txuas lus sib txawv. Peb cov khoom ntawm RF pem hauv ntej-kawg ua kom zoo tshaj plaws rau kev siv hauv kev sib txuas lus, aerospace, tiv thaiv, thiab lwm yam.
Xaus
RF pem hauv ntej-kawg yog qhov tseem ceeb ntawm txhua qhov kev sib txuas lus, kom ntseeg tau cov teeb liab kis tau zoo thiab txais tos thaum txo kev cuam tshuam. Nrog rau kev nce qib hauv kev siv thev naus laus zis thiab kev xav tau ntau dua rau kev ua tau zoo dua, qhov tseem ceeb ntawm cov kev daws teeb meem zoo RF pem hauv ntej tseem nce ntxiv, ua rau lawv yog ib qho tseem ceeb hauv kev sib txuas lus niaj hnub wireless.
