Dusha sare ee Buur Baluns RF Mikrowave Millimeter Wave mm hir
Dusha sare ee Buur Baluns (Balance-Unbalance Transformers) waa qaybo RF/microwave khaas ah oo loogu talagalay in lagu beddelo inta u dhaxaysa calaamadaha korantada ee dheellitiran iyo kuwa aan dheellitirnayn ee wareegyada soo noqnoqda. Lagu soo saaray iyadoo la adeegsanayo tignoolajiyada dhoobada dhuuban ee horumarsan ama lakabyo badan, aaladahan is haysta waxay bixiyaan beddelka caqabada muhiimka ah iyo awoodaha diidmada qaab-dhismeedka caadiga ah. Sida dhismooyinka muhiimka ah ee nidaamyada wireless-ka, waxay fududeeyaan hufnaanta calaamadda ugu wanaagsan iyagoo raacaya hababka isku-dhafka otomaatiga ah ee casriga ah. Naqshadaynta dusha sare waxay ka dhigaysa inay ku habboon yihiin wax soo saarka mugga sare ee isgaarsiinta, IoT, iyo codsiyada macaamiisha elektiroonigga ah.
Astaamaha iyo Astaamaha Muhiimka ah:
1. Waxqabadka soo noqnoqda sare iyo injineernimada saxda ah
Hawlgalka Broadband: Taageero kala duwanaansho badan oo soo noqnoqota ah (laga bilaabo dhowr MHz ilaa kooxo badan oo GHz ah) oo leh waxqabad joogto ah oo dhex mara xajmiyada xaddidan, baabi'inta baahida qaybo badan oo cidhiidhi ah.
Isbeddelka is-beddelka saxda ah: Bixi saamiga beddelka impedance saxda ah (tusaale, 1:1, 1:4, 4:1) oo leh dulqaad adag (± 5% caadiga ah) si loo waafajiyo shuruudaha nidaamka kala duwan iyo hal-dhammaad.
Balaadhan/ dheelitirnaanta wejiga: Ilaali dheelitirnaanta baaxadda sare (sida caadiga ah ± 0.5 dB) iyo dheelitirka wajiga (caadiyan ± 5 darajo) si wax ku ool ah diidmada qaylada caadiga ah ee qaabka caadiga ah.
Luminta gelinta hoose: Gaadhi khasaaraha ugu yar ee calaamadda (sida ugu hooseeya 0.5 dB iyada oo ku xidhan inta jeer ee soo noqnoqda) iyada oo loo marayo isku-xidhka birlabeedka la hagaajiyay iyo agabka tamarta-khasaare hooseeya.
2. Baakadaha horumarsan iyo awoodaha isdhexgalka
Qodobbada qaabka is haysta: Waxaa lagu heli karaa baakadaha heerka warshadaha iyo cabbirada gaarka ah ee nashqada xaddidan.
Waafaqsanaanta Buur-korka: La jaanqaadi karta qalabka qaadista-iyo-meelaynta otomaatiga ah iyo dib-u-qulqulka hababka alxanka, awood u siinaya wax soo saarka mugga sare.
Dhisme adag: Isticmaal dhoobada, ferrite, ama substrate-ka isku dhafan ee leh dhammaadka (Ni/Sn, Au) oo ku habboon xaaladaha deegaanka ee adag.
ESD iyo ilaalinta kulaylka: Tilmaamaha ilaalinta isku dhafan waxay u adkaysanayaan dhacdooyinka ESD (ilaa 2kV HBM) iyo heerkulka shaqaynta.
3. Kalsoonida la xoojiyey iyo hagaajinta gaarka ah ee codsiga
Waxqabad sare oo go'doon ah: Bixi go'doon deked-ilaa-deke sida caadiga ah ka badan 20 dB si looga hortago isku-xidhka calaamadaha aan la rabin.
Awooda wax ka qabashada awooda: Taageerida heerarka korantada min milliwatts ilaa dhowr watts iyadoo ku xiran cabbirka xirmada iyo naqshadeynta.
Hagaajinta qaabka gaarka ah: Waxaa lagu heli karaa qaabaynta loo habeeyay codsiyada gaarka ah (Wi-Fi, gacanta, Bluetooth, iwm.) oo leh S-parameters sifeed.
Codsiyada:
1. Nidaamyada isgaarsiinta wireless-ka
Kaabayaasha gacanta: transceivers saldhiga saldhiga, nidaamyada MIMO ee waaweyn, iyo unugyo yaryar oo u baahan iswaafajinta iswaafajinta iyo qaabka caadiga ah ee diidmada hore ee RF.
