Sichuan Keenlion Tignoolajiyada Microwave——Isku-darka

Sichuan Keenlion Tiknoolajiyada Microwave ee la aasaasay 2004, Sichuan Keenlion Mircrowave teknoolajiyada CO., Ltd. waa soo saaraha ugu horreeya ee qaybaha Mircrowave Passive ee Sichuan Chengdu, Shiinaha.

Waxaan bixinaa wax qabad heer sare ah qaybaha mirrowave iyo adeegyada la xidhiidha codsiyada microwave ee gudaha iyo dibaddaba. Alaabooyinku waa kuwo kharash-ool ah, oo ay ku jiraan awood qaybiye kala duwan, lamaanayaasha jihada, filtarrada, isku-dariyeyaasha, duplexers, qaybaha dadban ee la habeeyey, go'dooyeyaasha iyo wareegayaasha. Alaabadayada waxaa si gaar ah loogu talagalay deegaan iyo heerkul aad u daran. Qeexitaannada waxaa loo qaabayn karaa iyadoo loo eegayo shuruudaha macaamiisha waxaana lagu dabaqi karaa dhammaan xargaha soo noqnoqda ee caadiga ah iyo kuwa caanka ah ee leh xajmiyada kala duwan ee DC ilaa 50GHz.

Isku-darka

Nidaamka isgaadhsiinta mobaylada ee bilaa-waayirka ah, shaqada ugu weyn ee isku-darka waa in la isku daro calaamadaha band-yada badan ee soo-gelinta oo loo soo saaro isla nidaamka qaybinta gudaha.

Codsiga injineernimada, 800MHz C network, 900MHz G network ama soo noqnoqoshada kale duwan waxay u baahan yihiin in la soo saaro isku mar. Isticmaalka isku-darka, qayb ka mid ah nidaamka qaybinta gudaha ayaa ku shaqayn kara bandowga soo noqnoqda ee CDMA, guutooyinka soo noqnoqda ee GSM ama xargaha soo noqnoqda ee kale isku mar.

Tusaale ahaan, nidaamka anteenada raadiyaha, calaamadaha soo-gelinta iyo soo-saarka ee dhowr xabbo oo soo noqnoqda oo kala duwan (sida 145mhz iyo 435mhz) ayaa lagu daraa isku-darka, ka dibna lagu xiro raadiyaha oo leh feeder, taas oo aan badbaadin oo kaliya, laakiin sidoo kale ka fogaanaysa dhibaatada beddelka anteenooyinka kala duwan.

 

 

Esaamayn

Codsiyada injineernimada, waxaa lagama maarmaan ah in la isku daro shabakada 800MHz C iyo shabakadda 900MHz G. Isticmaalka isku-darka, qayb ka mid ah nidaamka qaybinta gudaha ayaa ka shaqayn kara kooxda CDMA iyo guutada GSM isku mar. Tusaale kale, nidaamka anteenada raadiyaha, calaamadaha soo-gelinta iyo soo-saarka ee dhowr xabbo oo soo noqnoqda oo kala duwan (sida 145mhz iyo 435mhz) ayaa la isku daraa isku-darka, ka dibna lagu xiro raadiyaha oo leh feeder, kaas oo aan badbaadin oo kaliya ee feederiyaha, laakiin sidoo kale ka fogaanaya dhibaatada beddelka anteenooyinka kala duwan..

 

Sharaxaada u dhiganta mabda'a

Isku-darka guud ahaan waxaa loo isticmaalaa dhamaadka gudbinta. Shaqadeedu waa in ay isku geyso laba ama in ka badan oo calaamadaha RF ah oo laga soo diro gudbiyeyaal kala duwan oo ay u dirto aaladaha RF ee ay anteenadu gudbiso, iyada oo laga fogaanayo isdhexgalka calaamadaha deked kasta.

Isku-dariyeyaasha guud ahaan waxay leeyihiin laba dekedood ama ka badan oo wax-soo-saarka ah iyo hal deked oo wax-soo-saar ah oo keliya. Go'doominta dekeddu waa tilmaame muhiim ah oo lagu qeexo awoodda laba calaamadood oo aanay midba midka kale saamaynayn. Guud ahaan waxaa loo baahan yahay in ka badan 20dB.

Isku-darka buundada 3dB wuxuu leeyahay laba dekedood oo wax-ku-soo-gal ah iyo laba dekedood oo wax-soo-saar leh, sida ku cad sawirka 2. Waxaa caadi ahaan loo isticmaalaa in lagu farsameeyo laba jeer oo xambaara wireless-ka oo lagu quudiyo anteeno ama nidaamka qaybinta. Haddii hal deked oo kaliya la isticmaalo, dekedda kale ee wax soo saarka waxay u baahan tahay in lagu xidho culays 50W ah. Waqtigaan, waxaa jira khasaaro 3dB ka dib marka la isku daro calaamadaha. Mararka qaarkood labada dekedood ee wax soo saarka ayaa loo baahan yahay in la isticmaalo, markaa ma jiraan wax rar ah iyo khasaare 3dB ah.

Isku-dubarid helista iyo dirida taleefanka gacanta ee signalka hal anteeno. Nidaamka GSM-ka, sababtoo ah transceiver-ku kuma jiro waqti isku mid ah, taleefoonka gacanta ayaa ka tagi kara duplexer si uu u go'doomiyo transceiver, oo kaliya isticmaalo isku-darka transceiver-ka fudud si uu isugu daro diritaanka iyo helitaanka signalada hal anteeno ah iyada oo aan la faragelinin midba midka kale.

Wareegga helitaanka, anteenadu waxay helaysaa calaamadda, waxay gashaa kanaalka helitaanka iyada oo loo marayo isku-darka, waxay ku qastaa calaamadda oscillator-ka maxalliga ah ee la helay (tusaale, calaamadda VCO ee la helay ee ay keentay soo-saareyaha soo noqnoqda), waxay beddeshaa calaamadda soo noqnoqda sare ee signalka soo noqnoqda dhexdhexaadka ah, ka dibna quadrature wuxuu hoos u dhigayaa calaamadda si uu u dhaliyo calaamadaha I iyo Q ee la helay; Dabadeed GMSK (Gaussian filter ugu yaraan furaha isbeddelka ugu yar ee soo noqnoqda) ayaa la sameeyaa si loogu beddelo calaamadda analoogga ah ee signalada dhijitaalka ah, ka dibna loo diro qaybta farsamaynta baska.

Wixii wareegga gudbinta, qaybta baseband waxay soo dirtaa socodka xogta jir ee TDMA (oo leh heerka 270.833kbit / s) ee GSMK modulation si loo sameeyo gudbinta I iyo Q calaamadaha, kuwaas oo markaa loo diro gudbinta kor u qaadida si loogu beddelo bandowga gudbinta. Kordhinta awoodda ka dib, gudbiyaha ayaa u soo diraya anteenada.

Soo noqnoqoshada soo noqnoqda waxay bixisaa calaamada oscillator-ka maxalliga ah ee lagama maarmaanka u ah beddelka soo noqnoqda ee gudbinta iyo qaybinta soo-gaadhista, waxayna isticmaashaa tignoolajiyada loop-ka xiran si loo dejiyo inta jeer. Waxay ka helaysaa tixraaca soo noqnoqda ee wareegga tixraaca saacadda.

Wareegga tixraaca saacaddu guud ahaan waa saacadda 13mhz. Dhanka kale, waxay bixisaa tixraaca saacada wareegga isku-dhafka soo noqnoqda iyo saacadda shaqada ee wareegga macquulka ah.

Kala soocida ugu weyn

Isku-duwaha laba jeer ee soo noqnoqda

① JCDUP-8019

GSM & 3G-dual soo noqnoqoshiyaha isku dhafka ah waa laba gudaha iyo mid dibadda ah. Calaamadaha GSM (885-960mhz) waxaa lagu dari karaa signalka 3G (1920-2170MHz).

② JCDUP-8028

DCS & 3G-dual soo noqnoqoshiyaha isku dhafka ah waa laba gudaha iyo mid dibadda ah. Digniinta DCS (1710-1880mhz) waxaa lagu dari karaa calaamadda 3G (1920-2170MHz).

③ JCDUP-8026B

(TETRA / IDEn / CDMA / GSM) & (DCS / PHS / 3G / WLAN) isku-darka soo noqnoqda laba-geesoodka ah waa laba gudaha iyo mid dibadda ah. Mid ka mid ah dekeddu waxay dabooshaa tetra/ident, CDMA iyo GSM band soo noqnoqoshada nidaamka (800-960MHz), waxayna geli kartaa tetra/ident, CDMA, GSM ama isku darka kasta; Dekadda kale waxay dabooshaa xadhkaha soo noqnoqda ee DCS, PHS, 3G iyo nidaamka WLAN (1710-2500mhz), waxayna gelin kartaa DCS, PHS, 3G, WLAN ama isku darka kasta oo iyaga ah.

④ JCDUP-8022

(CDMA / GSM / DCS / 3G) & WLAN laba jeer isku darka soo noqnoqda waa laba gudaha iyo mid dibadda ah. Mid ka mid ah dekeddu waxay dabooshaa CDMA, GSM, DCS iyo 3G band soo noqnoqda nidaamka (824-960 / 1710-2170mhz), waxayna geli kartaa CDMA, GSM, DCS, 3G ama isku darka kasta; Dekadda kale waxa ay dabooshaa xargaha soo noqnoqda ee nidaamka WLAN (2400-2500mhz) oo waxa ay gelin kartaa calaamadaha nidaamka WLAN.

Saddex jeer isku dhafka

① JCDUP-8024 / JCDUP-8024B

GSM & DCS & 3G saddexda jeer ee isku-darka ah waa saddex gudaha iyo mid dibadda ah. GSM (885-960mhz), DCS (1710-1880mhz) iyo 3G (1920-2170MHz) calaamadaha waa la isku dari karaa.

② JCDUP-8018

GSM & 3G & WLAN saddexda soo noqnoqda isku-darka waa saddex gudaha iyo hal dibadda ah. GSM (885-960mhz), 3G (1920-2170MHz) iyo WLAN (2400-2500mhz) calaamadaha waa la isku dari karaa.

Afar jeer isku-darka

① JCDUP-8031

GSM & DCS & 3G & WLAN afar soo noqnoqda isku-darka waa afar ku jira hal qalab. GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) iyo WLAN (2400-2483.5mhz) afar calaamadaha soo noqnoqda waa la isku dari karaa.

Intaa waxaa dheer, codsiga isku-darka, waa in la ogaadaa in habka quudinta calaamadaha ee saldhigga saldhigga ama soo noqnoqda uu yahay wireless, iyo isha ay ka soo jeedaan ballaaran. Sidaa darteed, baararka cidhiidhiga ah ayaa loo baahan yahay xaaladaha qaarkood si loo hubiyo nadiifnimada calaamadda; Habka quudinta calaamadda isku-darka waa fiilo, calaamaduna si toos ah ayaa looga soo qaadaa isha, taas oo ah calaamad cidhiidhi ah. Tusaale ahaan, kanaalka CDMA/GSM ee isku-darka jcdup-8026b wuxuu leeyahay ballac kanaalka 800-960MHz. Marka la gelayo calaamadda soo noqnoqoshada side GSM, sababtoo ah isha waa calaamadda soo noqnoqoshada side, habka quudinta waa fiilo, oo waxaa jira calaamada soo noqnoqda ee kanaalka iyada oo aan lahayn calaamado kale oo faragelin ah. Sidaa darteed, naqshadeynta kanaalka ballaaran ee isku-darka waa mid macquul ah oo ku habboon codsiga.
