Tiknoolajiyada Microwave-ka Sichuan Keenlion——Isku-darka

Tiknoolajiyadda Microwave-ka ee Sichuan Keenlion Waxaa la aasaasay 2004, Sichuan Keenlion Mircrowve techenology CO., Ltd. waa soo saaraha ugu horreeya ee qaybaha Passive Mircrowve ee Sichuan Chengdu, Shiinaha.

Waxaan bixinaa qaybo muraayado ah oo waxqabad sare leh iyo adeegyo la xiriira codsiyada microwave-ka gudaha iyo dibadda. Badeecadu waa kuwo kharash-ool ah, oo ay ku jiraan qaybiyayaal awood kala duwan, isku-xidhayaal jihooyin ah, shaandhooyin, isku-darka, laba-laab-qaybiyeyaal, qaybo aan firfircoonayn oo la habeeyey, go'doomiyayaal iyo wareegiyeyaal. Badeecadahayagu waxaa si gaar ah loogu talagalay deegaanno iyo heerkul kala duwan oo aad u daran. Tilmaamaha waxaa loo samayn karaa iyadoo loo eegayo shuruudaha macaamiisha waxaana lagu dabaqi karaa dhammaan xargaha soo noqnoqda ee caadiga ah iyo kuwa caanka ah oo leh bandwidyo kala duwan laga bilaabo DC ilaa 50GHz.

Isku-darka

Nidaamka isgaarsiinta moobaylka ee bilaa-waayirka ah, shaqada ugu weyn ee isku-darka waa inuu isku daro calaamadaha gelinta badan ee kooxaha oo uu u soo saaro isla nidaamka qaybinta gudaha.

Codsiga injineernimada, shabakadda 800MHz C, shabakadda 900MHz G ama mawjado kale oo kala duwan ayaa loo baahan yahay in la soo saaro isku mar. Iyada oo la adeegsanayo isku-darka, nidaam qaybinta gudaha ah ayaa ka shaqayn kara isku-xirka CDMA, kooxda soo noqnoqda GSM ama kooxaha soo noqnoqda ee kale isku mar.

Tusaale ahaan, nidaamka anteenada raadiyaha, calaamadaha soo gelinta iyo soo saarista ee dhowr xarig oo soo noqnoqda oo kala duwan (sida 145mhz iyo 435mhz) ayaa lagu daraa isku-darka, ka dibna waxaa lagu xiraa saldhigga raadiyaha iyadoo la adeegsanayo quudiye, kaas oo aan kaliya badbaadinayn quudiyaha, laakiin sidoo kale ka fogaanaya dhibaatada beddelka anteenooyinka kala duwan.

 

 

Esaameyn

Codsiyada injineernimada, waxaa lagama maarmaan ah in la isku daro shabakadda 800MHz C iyo shabakadda 900MHz G. Iyada oo la adeegsanayo isku-darka, nidaam qaybin gudaha ah ayaa isku mar ka shaqayn kara xarigga CDMA iyo xarigga GSM. Tusaale kale, nidaamka anteenada raadiyaha, calaamadaha soo gelinta iyo soo saarista ee dhowr xarig oo soo noqnoqda oo kala duwan (sida 145mhz iyo 435mhz) ayaa lagu daraa isku-darka, ka dibna waxaa lagu xiraa saldhigga raadiyaha quudiye, kaas oo aan kaliya badbaadin quudiye, laakiin sidoo kale ka fogaanaya dhibaatada beddelka anteenooyinka kala duwan..

 

Sharaxaadda isbarbardhigga mabda'a

Isku-darka waxaa guud ahaan loo isticmaalaa dhammaadka gudbinta. Shaqadiisu waa inuu isku daro laba ama in ka badan oo calaamadaha RF ah oo laga soo diro gudbiyeyaal kala duwan hal mid oo uu u diro aaladaha RF ee ay gudbiso anteenadu, iyadoo laga fogaanayo isdhexgalka calaamadaha deked kasta.

Isku-darkayaashu guud ahaan waxay leeyihiin laba ama in ka badan oo dekedo wax-soo-saar ah iyo hal deked oo wax-soo-saar ah oo keliya. Go'doominta dekeddu waa tusmo muhiim ah oo lagu qeexayo awoodda laba calaamadood aysan isku saameyn. Guud ahaan waxaa looga baahan yahay inay ka badan tahay 20dB.

Isku-darka buundada 3dB wuxuu leeyahay laba dekedood oo la geliyo iyo laba dekedood oo wax soo saar ah, sida ku cad Jaantuska 2. Waxaa caadi ahaan loo isticmaalaa in lagu sameeyo laba mawjadood oo sideyaal bilaa-waayir ah oo lagu quudiyo anteenada ama nidaamka qaybinta. Haddii hal dekedood oo wax soo saar ah la isticmaalo, dekedda kale ee wax soo saarka waxay u baahan tahay in lagu xiro culays 50W ah. Waqtigan xaadirka ah, waxaa jira khasaaro 3dB ah ka dib marka calaamadda la isku daro. Mararka qaarkood labada dekedood ee wax soo saarka ayaa loo baahan yahay in la isticmaalo, markaa ma jiraan wax culays ah iyo khasaaro 3dB ah.

Isku dar helitaanka iyo dirista taleefanka gacanta ee calaamadda hal anteeno. Nidaamka GSM, maadaama gudbiyuhu aanu ku jirin waqti isku mid ah, taleefanka gacantu wuxuu ka tagi karaa laba-laablaha si uu u kala saaro gudbiyaha, wuxuuna isticmaali karaa oo keliya isku-darka gudbiyaha fudud si uu isugu daro calaamadaha dirista iyo kuwa qaata hal anteeno iyada oo aan la faragelin midba midka kale.

Wareegga qaataha, anteenadu waxay heshaa calaamadda, waxay gashaa kanaalka qaataha iyada oo loo marayo isku-darka, waxayna ku dhex milmaysaa calaamadda oscillator-ka maxalliga ah ee la helay (tusaale ahaan calaamadda VCO ee la helay oo ay soo saarto isku-darka soo noqnoqda), waxay calaamadda soo noqnoqoshada sare u beddeshaa calaamad soo noqnoqota oo dhexdhexaad ah, ka dibna afargeeslaha ayaa hoos u dhiga calaamadda si loo soo saaro calaamadaha I iyo Q ee la helay; Kadib GMSK (Gaussian filter minimum frequency shift keying) ayaa la sameeyaa si calaamadda analoogga loogu beddelo calaamad dijitaal ah, ka dibna loo diro qaybta habaynta baseband.

Wareegga gudbinta, qaybta salka waxay u dirtaa qulqulka xogta qaab-dhismeedka TDMA (oo leh heer ah 270.833kbit / s) ee modulation-ka GSMK si loo sameeyo calaamadaha gudbinta I iyo Q, kuwaas oo markaa loo diro qalabka wareejinta gudbinta si loogu beddelo heerka soo noqnoqda gudbinta. Ka dib kordhinta awoodda, gudbiyaha ayaa u dira anteenada.

Soo-saareha soo noqnoqda wuxuu bixiyaa calaamadda oscillator-ka maxalliga ah ee lagama maarmaanka u ah beddelka soo noqnoqda ee cutubka gudbinta iyo helitaanka, wuxuuna adeegsadaa tignoolajiyada wareegga-xiran si uu u xasiliyo soo noqnoqoshada. Waxay ka heshaa tixraaca soo noqnoqda wareegga tixraaca saacadda.

Wareegga tixraaca saacaddu guud ahaan waa saacad 13mhz ah. Dhinac, waxay bixisaa tixraaca saacadda ee wareegga isku-darka soo noqnoqda iyo saacadda shaqada ee wareegga macquulka ah.

Kala-soocidda ugu Muhiimsan

Isku-darka soo noqnoqda ee laba-jibbaaran

① JCDUP-8019

Isku-darka laba-laab ee GSM & 3G waa aalad laba-gudbin iyo hal-bax ah. Calaamadda GSM (885-960mhz) waxaa lagu dari karaa calaamadda 3G (1920-2170MHz).

② JCDUP-8028

③ JCDUP-8026B

(TETRA / id / CDMA / GSM) & (DCS / PHS / 3G / WLAN) isku-darka laba-laabka ah waa aalad laba-gudbin iyo mid-bax ah. Hal deked ayaa daboola tetra / id, CDMA iyo GSM frequency band (800-960MHz), waxayna gelin kartaa tetra / id, CDMA, GSM ama isku-darka kasta; Dekedda kale waxay daboolaysaa frequency band ee nidaamka DCS, PHS, 3G iyo WLAN (1710-2500mhz), waxayna gelin kartaa DCS, PHS, 3G, WLAN ama isku-darka kasta oo iyaga ka mid ah.

④ JCDUP-8022

(CDMA / GSM / DCS / 3G) & isku-darka laba-laabka ah ee WLAN waa aalad laba-gudbin iyo hal-bax ah. Hal deked ayaa daboola xargaha soo noqnoqda ee nidaamka CDMA, GSM, DCS iyo 3G (824-960 / 1710-2170mhz), waxayna gelin kartaa CDMA, GSM, DCS, 3G ama isku-darka kasta; Dekedda kale waxay daboolaysaa xargaha soo noqnoqda ee nidaamka WLAN (2400-2500mhz) waxayna gelin kartaa calaamadaha nidaamka WLAN.

Isku-darka saddexda soo noqnoqoshada

① JCDUP-8024 / JCDUP-8024B

Isku-darka saddex-soo-noqnoqodka ee GSM & DCS & 3G waa qalab saddex-soo-gal ah iyo mid-goob ah. Calaamadaha GSM (885-960mhz), DCS (1710-1880mhz) iyo 3G (1920-2170MHz) waa la isku dari karaa.

② JCDUP-8018

Isku-darka saddex-murtiyeedka GSM & 3G & WLAN waa qalab saddex-gudbin iyo hal-gudbin ah. Calaamadaha GSM (885-960mhz), 3G (1920-2170MHz) iyo WLAN (2400-2500mhz) waa la isku dari karaa.

Isku-darka afar jeer

① JCDUP-8031

Isku-darka afar-soo-noqoshada ee GSM & DCS & 3G & WLAN waa qalab afar-soo-noqosho ah. GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) iyo WLAN (2400-2483.5mhz) afar calaamadood oo soo noqnoqda ayaa la isku dari karaa.

Intaa waxaa dheer, marka la adeegsanayo isku-darka, waa in la ogaadaa in habka quudinta calaamadda ee saldhigga saldhigga ama ku-celcelinta uu yahay mid aan lahayn fiilo, isha laga soo xigtayna ay tahay mid ballaaran. Sidaa darteed, marin-haweedka cidhiidhiga ah ayaa looga baahan yahay xaaladaha qaarkood si loo hubiyo daahirnimada calaamadda; Habka quudinta calaamadda ee isku-darka waa fiilo, calaamaddana si toos ah ayaa looga soo qaataa isha, taas oo ah calaamad cidhiidhi ah. Tusaale ahaan, kanaalka CDMA / GSM ee isku-darka jcdup-8026b wuxuu leeyahay ballac kanaal oo ah 800-960MHz. Marka la galayo calaamadda soo noqnoqoshada side GSM, maadaama isha ay tahay calaamad soo noqnoqoshada side, habka quudinta waa fiilo, waxaana jira oo keliya calaamaddan soo noqnoqoshada side ee kanaalka iyada oo aan lahayn calaamado faragelin kale. Sidaa darteed, naqshadeynta kanaalka ballaaran ee isku-darka ayaa suurtagal ah codsiga wax ku oolka ah.

Waxaan sidoo kale habayn karnaa qaybaha rf ee aan firfircoonayn iyadoo loo eegayo baahiyahaaga. Waxaad geli kartaa bogga habaynta si aad u bixiso qeexitaannada aad u baahan tahay.
