Millimeter-yoj (Mmwave) lim tshuab yog ib qho kev sib txuas lus tseem ceeb hauv kev sib tw ntawm lub cev ntawm lub cev, tab sis kev ua kom muaj kev thev taus, thiab qhov ntsuas kub thiab txias.
Nyob rau hauv lub realm ntawm mainstream 5g wireless kev sib txuas lus, lub ntsiab lus yav tom ntej yuav hloov mus rau kev siv lub zog ntawm Mmwave Spectrum, thaum kawg txhim kho kev kis tus nqi.
Nws yog cov paub zoo tias vim lawv cov siab ntau thiab tseem ceeb ploj, mmwave cov cim piav qhia cov tub ntxhais ib ce me. Cov kev kav hlau txais xov no tau muab faib ua ke los ua cov kab nqaim-nqaj, siab array antennas.
Ib qho ntawm cov teeb meem tseem ceeb hauv kev lim tsim cov lus dag hauv kev yoog raws li lub kav hlau txais xov ntev, tshwj xeeb tshaj yog rau cov ntxaij lim dej siab. Ib qho ntxiv, kev tsim tawm kev zam thiab qhov kub txav ntawm cov ntxaij lim dej cuam tshuam ntau rau txhua qhov ntawm cov khoom tsim thiab kev tsim khoom.
Qhov loj me txwv nyob hauv Mmwave Technology
Hauv cov kav hlau txais xov ib txwm array, qhov sib nrug ntawm cov ntsiab lus yuav tsum tsawg dua li ib nrab ntawm lub wavelength (λ / 2) kom zam dhau kev cuam tshuam. Lub ntsiab cai no sib npaug zos siv rau 5g nqajforming kav hlau txais xov. Piv txwv li, ib tus kav hlau txais xov ua haujlwm hauv 28 GHZ Band muaj qhov chaw nyob ntawm kwv yees li 5 mm.cononsententently, cov khoom siv tsis pub dhau ntawm cov array yuav tsum yog tsawg heev.
Pased arrays ua haujlwm hauv Mmwave daim ntawv thov feem ntau txais yuav cov qauv qauv tsim qauv (raws li cov kav hlau txais xov (PCBS) (thiab thaj chaw xiav) tuaj yeem sib txuas nrog lub kav hlau txais xov.
Qhov chaw ntawm cov rooj tsav tsheb Circuit Circuit Court yog qhov tsawg heev, tab sis kev lim dej uas muaj ntau dua thiab lwm cov hluav taws xob sib xyaw ua ke yuav tsum tau mounted ncaj qha rau sab nraum qab ntawm lub kav hlau txais xov.
Kev cuam tshuam ntawm kev tsim kho kom ntev ntawm cov ntxaij lim dej
Muab qhov tseem ceeb ntawm mmwave lim, kev tsim kho kev tiv thaiv ua si ib tug pivotal lub luag hauj lwm, cuam tshuam rau ob qho kev lim dej thiab tus nqi.
Txhawm rau tshawb xyuas cov xwm txheej no, peb piv peb qhov sib txawv 26 GHz lim tsim cov txheej txheem:
Cov lus qhia hauv qab no tau muaj kev pab ntau yam muaj nyob hauv ntau lawm:
Kev Ua Phem Rau Cov Ntxhw PCB Micb Micrters
Raws li muaj xwm txheej hauv qab no, Microstrip Lim tsim yog shoitcased.
Tus tsim kev txiav nkhaus yog raws li hauv qab no:
Txhawm rau kawm qhov kev ua kom muaj txiaj ntsig ntawm PCB microstrip lim, yim muaj peev xwm txaus siab tau xaiv, pom qhov sib txawv.
Kev Ua Phem Rau Cov Lim Page PCB
Qhov tsim qauv lim sib xyaw, muaj nyob hauv qab no, yog ib qho qauv xya-theem nrog 30 mil Ro3003 Dielectric laug cam ntawm sab saum toj thiab hauv qab.
Lub yob-tawm yog tsawg dua ntxhab, thiab cov duab sib dhos yog qhov tsis txaus ntseeg ntawm lub caij nplooj zeeg, ua rau suboptimal harmand kev ua tau zoo ntawm cov neeg nyob deb.
Ib yam li ntawd, kev soj ntsuam kev ua siab ntev qhia tau qhia zoo dua cov kev xav zoo dua piv rau microTrip kab.

Rau 5g wireless kev sib txuas lus kom ua tiav nrawm nrawm, Mmwave Lim Technology kev ua haujlwm ntawm 20 Ghz lossis ntau zaus yog qhov tseem ceeb. Txawm li cas los xij, cov kev sib tw ua rau ntawm lub cev nqaij daim tawv, kev ua siab ntev, thiab kev tsim khoom lag luam.
Yog li, kev cuam tshuam ntawm kev ua siab ntev ntawm kev tsim qauv yuav tsum tau ua tib zoo txiav txim siab. Nws yog pom tseeb tias SMT lim pom zoo tshaj qhov ruaj khov dua li microstrip thiab cov ntxaij lim dej uas yog qhov kev xaiv ntawm lub neej yav tom ntej Mmwave kev sib txuas lus.
