Kev nthuav dav ntawm 4G LTE tes hauj lwm, kev xa tawm ntawm 5G tes hauj lwm tshiab, thiab kev nyob txhua qhov chaw ntawm Wi-Fi ua rau muaj kev nce ntxiv ntawm cov xov tooj cua zaus (RF) uas cov khoom siv wireless yuav tsum txhawb nqa. Txhua qhov band xav tau cov lim dej rau kev cais tawm kom khaws cov teeb liab nyob hauv "kab" kom raug. Thaum tsheb khiav ntau ntxiv, cov kev cai yuav nce siab kom tso cai rau cov teeb liab tseem ceeb hla dhau tau zoo, tiv thaiv kev siv roj teeb ntau dhau thiab nce cov nqi ntaub ntawv. Cov lim dej yog qhov tseem ceeb rau kev siv bandwidth dav thiab muaj peev xwm zaus siab, nrog rau qhov nyuaj tshaj plaws yog Wi-Fi 6E tshiab nrog bandwidth ntawm 6.1MHz thiab zaus siab tshaj plaws ntawm 200.7 GHz.
Nrog rau kev siv ntau dua thiab ntau dua ntawm 5GHz - 3GHz zaus rau 7G thiab Wi-Fi, kev cuam tshuam ntawm cov bands yuav ua rau muaj kev cuam tshuam rau kev sib koom ua ke ntawm cov thev naus laus zis wireless no thiab txwv lawv cov kev ua tau zoo. Yog li ntawd, xav tau cov lim dej ua haujlwm siab dua los tswj kev ncaj ncees ntawm txhua band. Tsis tas li ntawd, tus lej tsawg ntawm cov antennas muaj nyob rau hauv cov khoom siv mobile thiab APs yuav tsav tsheb hloov pauv architecture kom nce kev siv ntawm kev sib koom antenna, uas yuav ua rau cov kev xav tau ntawm cov lim dej ua haujlwm ntxiv.
Cov thev naus laus zis lim dej yuav tsum txuas ntxiv hloov zuj zus kom tau raws li qhov xav tau ntawm Wi-Fi 6 thiab Wi-Fi 6E tshiab nrog rau 5G kev ua haujlwm. Cov thev naus laus zis lim dej yav dhau los siv rau hauv cov ntawv thov wireless xws li Surface Acoustic Wave (SAW), Temperature Compensated SAW (TC-SAW), Solidly Mounted Resonator-Bulk Acoustic Wave (SMR-BAW), thiab Film Bulk Acoustic Resonators (FBAR) tuaj yeem nthuav dav mus rau qhov dav dua bandwidths thiab cov zaus siab dua tab sis ntawm tus nqi ntawm lwm cov kev ntsuas tseem ceeb xws li kev poob thiab lub zog ruaj khov. Lossis, ntau lub lim dej tuaj yeem npog cov bandwidths dav, siv ua ke nrog cov lim dej tsis yog acoustic lossis ua ntau ntu.
Nrog kev hloov kho tshiab ntawm kev lim dej ua haujlwm siab, qhov tshwm sim yuav yog cov ntaub ntawv siab dua, qis dua latency, thiab muaj zog dua. Txhua tus neeg tau ntsib kev hu video stalling, gaming lagging, thiab poob kev sib txuas hauv tsev thaum lub sijhawm ua haujlwm deb. Cov thev naus laus zis Wi-Fi tshiab ua ke nrog cov zaus bandwidth dav tshiab uas tiv thaiv los ntawm kev lim dej siab heev yuav muab cov kev daws teeb meem mus tom ntej. Cov lim dej no yuav pab ua tiav cov bandwidth dav uas xav tau, kev ua haujlwm zaus siab, kev poob qis, thiab kev tswj hwm lub zog siab. Piv txwv li, XBAR raws li cov thev naus laus zis resonator loj (BAW). Cov resonators no muaj cov siv lead ua ib leeg, txheej piezoelectric, thiab cov hlau tines ntawm qhov saum npoo raws li interdigitated (IDT) transducer.
Cov lim dej Hybrid integrated passive device (IPD) FBAR Wi-Fi 6E tsuas yog muab kev tiv thaiv kev cuam tshuam rau cov 5 GHz bands uas tsis tau tso cai thiab tsis yog rau 5G sub-6GHz lossis UWB channels, thaum XBAR Wi-Fi 6E lim tiv thaiv Wi-Fi 6E bands los ntawm txhua qhov teeb meem cuam tshuam.
Cov ntxaij lim dej RF rau Wi-nkaus 7
Wi-Fi ua kom tiav cov tes hauj lwm cellular hauv kev ua kom tau raws li qhov xav tau ntawm lub peev xwm thiab cov ntaub ntawv ceev. Wi-Fi 6 thiab cov spectrum nce ntxiv ua rau Wi-Fi nyiam dua. Txawm li cas los xij, kev sib koom ua ke ntawm Wi-Fi thiab 5G yuav xav tau cov lim dej los daws cov teeb meem cuam tshuam. Cov lim dej no yuav tsum muab cov bandwidth dav, kev ua haujlwm zaus siab, kev poob qis, thiab kev tswj hwm lub zog siab. Nrog rau daim ntawv pov thawj ntawm Wi-Fi 7 cov khoom siv xav tias yuav tshwm sim thaum ntxov xyoo 2024, qhov xav tau cov lim dej kom ua tau raws li cov kev cai nruj dua yuav tsuas yog nce ntxiv. Tsis tas li ntawd, kev hloov pauv tom qab muaj kev sib kis hauv kev ua neej thiab chaw ua haujlwm txhais tau tias yuav tsuas yog muaj ntau hom khoom siv tshiab thiab cov ntawv thov uas tshaib plab.
Chengdu Concept Microwave yog cov chaw tsim khoom tshaj lij ntawm cov lim dej RF hauv Suav teb, suav nrog RF lowpass lim, highpass lim, bandpass lim, notch lim / band nres lim, duplexer. Tag nrho lawv tuaj yeem hloov kho raws li koj cov kev xav tau.
