RF pem hauv ntej-kawg module: cov tub ntxhais tsav tsheb ntawm 5G era

RF pem hauv ntej-kawg module (FEM) ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus wireless niaj hnub, tshwj xeeb tshaj yog nyob rau hauv 5G era. Nws yog tsim los ntawm cov khoom tseem ceeb xws li lub zog amplifier (PA),lim,duplexer, RF hloov thiabTsawg suab nrov amplifier (LNA)los xyuas kom meej lub zog, stability thiab zoo ntawm lub teeb liab.

Lub hwj chim amplifier yog lub luag hauj lwm rau amplifying lub teeb liab RF, tshwj xeeb tshaj yog nyob rau hauv 5G, uas yuav tsum tau high efficiency thiab high linearity. Lub lim xaiv ib lub teeb liab tshwj xeeb los lim tawm cov teeb liab cuam tshuam los xyuas kom meej qhov purity ntawm cov teeb liab kis tau tus mob. Nyob rau hauv lub siab zaus band, nto acoustic yoj (SAW) thiab bulk acoustic yoj (BAW) lim muaj lawv tus kheej zoo thiab qhov tsis zoo. BAW cov ntxaij lim dej ua tau zoo dua nyob rau hauv lub siab zaus band, tab sis tus nqi siab dua.

Covduplexertxhawb kev sib faib ntau zaus duplex (FDD) kev sib txuas lus los xyuas kom meej qhov ua tau zoo ntawm kev sib txuas lus ob txoj kev, thaum lub RF hloov yog lub luag hauj lwm rau kev hloov cov teeb liab txoj kev, tshwj xeeb tshaj yog nyob rau hauv 5G multi-band ib puag ncig, uas yuav tsum tau tsawg insertion poob thiab ceev hloov. CovTsawg suab nrov amplifierxyuas kom meej tias lub teeb liab tsis muaj zog tau txais tsis cuam tshuam los ntawm lub suab nrov.

Nrog rau kev txhim kho ntawm 5G thev naus laus zis, RF pem hauv ntej-kawg modules tau txav mus rau kev koom ua ke thiab kev ua haujlwm me me. SiP ntim tshuab ntim ntau yam khoom siv RF ua ke, txhim kho kev sib koom ua ke thiab txo cov nqi. Nyob rau tib lub sijhawm, daim ntawv thov ntawm cov ntaub ntawv tshiab xws li kua siv lead ua kua polymer (LCP) thiab hloov kho polyimide (MPI) hauv cov kav hlau txais xov teb ntxiv txhim kho cov teeb liab kis tau tus mob.

Kev tsim kho tshiab ntawm RF pem hauv ntej-kawg modules tau txhawb nqa kev nce qib ntawm 5G kev sib txuas lus, thiab yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus wireless yav tom ntej, coj ntau txoj hauv kev rau kev txhim kho thev naus laus zis.
