Kusanthula ukadaulo wa RF pokana ndi kuwunika

Rf oletsa (makanema ojambula) otsutsa) ndizofunikira kwambiri pamabwalo a RF, zomwe zidapangidwira kuti zizindikiritse zizindikiro, zofananira, komanso kugawa malo apamwamba kwambiri. Amasiyana kwambiri kuchokera muyezo wokhazikika poletsa kuchuluka kwa zochitika zapamwamba, kusankha kwa zinthu zakuthupi, komanso kapangidwe kake, ndikuwapangitsa kukhala ofunikira polumikizirana, zida za radar, ndi zina zambiri. Nkhaniyi ikuwunikira mwatsatanetsatane za mfundo zawo zamaukadaulo, kupanga njira, mawonekedwe a pakati, komanso ntchito wamba.

Makhalidwe apamwamba kwambiri ndi zochitika za parasitic
RF Otsutsa ayenera kukhala osasunthika pamayendedwe apamwamba (MHZ to GHz), kufunikira zokambirana za parasitic kugwirizanitsa ndi cabwinocation. Okhazikika wamba amavutika chifukwa cha kutsogolera ndi kuthandizira, zomwe zimapangitsa kupatuka kupatuka pamagulu apamwamba. Njira zazikuluzikulu zimaphatikizapo:

Njira zochepetsetsa / zandiweyani zotsika mtengo.

Makina osasinthika: Kuzungulira kwa njoka kapena njoka kutsutsa minda yamagetsi yomwe imapangidwa ndi njira zamakono, zimachepetsa malingaliro otsika ngati 0.1Nh.

Kusokoneza mafayilo ndi magetsi osungunuka

Mafashoni ofananira: rf oletsa kusunthika (mwachitsanzo, 50ω / 75ω) Pafupifupi ma bandwidths (mwachitsanzo, DC ~ 40

Kugwira Mphamvu: Mphamvu Yokwera Kwambiri Kugwiritsa ntchito njira zotsutsana ndi zoopsa (mwachitsanzo, al₂o₃ / Aln Centramics) ndi magetsi amphamvu mpaka makumi asanu ndi limodzi (mwachitsanzo, 100W @GW @Goz).

Kusankha Zinthu

Zovuta zakugonjetsedwa: Zokwera kwambiri, zida zotsika kwambiri (mwachitsanzo, tan, nicr) onetsetsani kuti matenthedwe otsika (<50ppm / ℃) komanso kukhazikika kwapamwamba.

Zipangizo zopatsirana: Zochititsa chidwi-zowoneka bwino kwambiri (Al₂o₃, Aln) kapena magawo a PTFF) amachepetsa kutentha ndikuwonjezera kutentha.

Ii. Kupanga njira
Rf ogwiritsa ntchito bwino magwiridwe antchito komanso kudalirika. Njira zazikuluzikulu zimaphatikizapo:

Kutulutsa / kunenepa kwambiri

Kukula: Nano-scale yunifolomu mafilimu amasungidwa m'malo apamwamba, akukwaniritsa kulolera kwa 0,5%.

Kuchepetsa kwa laser: Kusintha kwa laser kumalepheretsa ku ± 0.1%.

Matekisoni

Mount-Mount (SMT): Mapaketi ang'onoakulu (mwachitsanzo, 0402, 0603) saitfoni ya 5G ndi ma module a IOT.

Masamba ogwirizana: Mgonero wachitsulo wokhala ndi mawonekedwe a sma / bnc amagwiritsidwa ntchito pogwiritsa ntchito mapulogalamu apamwamba (mwachitsanzo, ma radar zofala).

Kuyesa Kwambiri Kwambiri ndi Kale

Vector Netch Testrizer (vNA)

Kuchepetsa matenthedwe ndi mayeso okalamba: kumangirira kutentha kwakukulu ndikukhazikika kwa nthawi yayitali (mwachitsanzo, kuyesa kwa maola 1,000-kotchera).

Iii. Mawonekedwe
RF OGWIRA BWINO KWAMBIRI:

Kuchita pafupipafupi

Parasitictitics yotsika: Parasitic Prosuction <0.5Nh, Captacity <0.1pf, ndikuwonetsetsa khola mpaka ghz.

Kuyankha kwa Broadband: Kuthandiza DC ~ 110gz (mwachitsanzo, mmwave Bands) kwa 5g nr ndi satellite.

Mphamvu yayikulu komanso yoyendetsa mafuta

Mphamvu Zamphamvu: Kufikira 10w / mm, mipata ya Aln), yokhala ndi kulolera kwa chikhosi (mwachitsanzo, 1kW @ 1μs).

Kapangidwe kamene kamadzaza: Kutentha kwa kutentha kapena njira zozizira zozizira za maziko okwera ndi ma rayar.

Kukhazikika Kwachilengedwe

Kukhazikika kutentha: Magwiritsidwe ntchito kuchokera -55 ℃ mpaka + 200 ℃, kusonkhana Arospace zofunikira.

Kukana Kulimbana & Kusindikiza: Mil-std-810g-810g-810g-810g-asitikali ndi iP67 Fumbi / madzi kukana.

Iv. Zolemba wamba
Njira Zoyankhulirana

5g malo oyambira: ogwiritsidwa ntchito pa "

Microwave Backhaul: Cipangizo la a Omeniartor for Forcent Recotion (mwachitsanzo, 30DB).

Radar ndi ntchentche ya zamagetsi

Makina osokoneza bongo: Njira zotsalira zotsalira mu ma module a T / R kuteteza LNAS.

Makina a Jemiming: Yambitsani kugawa kwa mphamvu yamagetsi pazithunzi zingapo.

Kuyesa ndi kuyeza zida

Kusanthula kwa vekiton

Kuyesa Kwamphamvu: Ogwiritsa ntchito mphamvu zapamwamba amatenga mphamvu (mwachitsanzo, 10KV akupuma).

Zida zamankhwala ndi mafakitale

Mri RF Coils: Fananitsani poyambira kuti muchepetse zojambulajambula zoyambitsidwa ndi minofu.

Makina a plasma: Limbikitsani zotulutsa RF Poteteza kuwonongeka kwa ma Oscillations.

V. Zovuta ndi zomwe zikuchitika mtsogolo
Zovuta Zaukadaulo

Mapangidwe a Mmwave: Kupanga magulu oletsa> 110ghz kumafuna kuyankha khungu ndi kutayika kwa sekondale.

Kulekerera kwakukulu: Mphamvu yomweyo magetsi amapita kumafuna zinthu zatsopano (mwachitsanzo, ogwiritsa ntchito mwanzeru).

Zochitika Zachitukuko

Ma module ophatikizidwa: kuphatikiza kukana ndi zosefera / ma couns mu phukusi limodzi (mwachitsanzo, anyezi antennna ma module) kuti asunge malo a PCB.

Kuwongolera kwa Smart: Kuchuluka kutentha / ma exy amakongoletsa ofananira (mwachitsanzo, 6g kukonzanso malo otentha).

Zakudya zakuthupi: Zipangizo za 2D (mwachitsanzo, graphene) zitha kuthandizira kukula kwa ultraband, Kutayika kotsika kwambiri.

Vi. Mapeto
Monga "owalemba chete" a makina othamanga kwambiri, rf oletsa kufananiza, kudulira kwamphamvu, komanso kukhazikika pafupipafupi. Mapulogalamu awo adagwiritsa ntchito malo osungirako 500 Ndi kupititsa patsogolo kulumikizana kwa MMmave ndi Gemiconductor, a RF otsutsana nawo adzasinthira maulendo apamwamba, mphamvu yayikulu, komanso luntha, kukhala chofunikira kwambiri m'badwo wotsatira.
