Ikoranabuhanga rya Microwave ya Sichuan Keenlion——Umuhuza

Ikoranabuhanga rya Microwave ya Sichuan Keenlion ryashinzwe mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. niyo ikora ibikoresho bya Passive Mircrowave i Sichuan Chengdu, mu Bushinwa.

Dutanga ibice bya mirowave bikora neza cyane hamwe na serivisi zijyanye nabyo ku mikoroonde mu gihugu no mu mahanga. Ibicuruzwa birahendutse, birimo ibikoresho bitandukanye byo gutandukanya ingufu, ibikoresho byo guhuza icyerekezo, filters, combiners, duplexers, ibikoresho byihariye bya passive, insolators na circulators. Ibicuruzwa byacu byagenewe ibidukikije bitandukanye n'ubushyuhe bukabije. Ibisobanuro bishobora gukorwa hakurikijwe ibyo abakiriya bakeneye kandi bikoreshwa ku miyoboro yose isanzwe kandi ikunzwe ifite bandwidth zitandukanye kuva kuri DC kugeza kuri 50GHz.

Umuhuza

Muri sisitemu y'itumanaho igendanwa idakoresha umugozi, akazi k'ingenzi ka combiner ni uguhuza ibimenyetso by'itumanaho ryinjira mu matsinda menshi no kubishyira muri sisitemu imwe yo gukwirakwiza amakuru imbere mu nzu.

Mu ikoreshwa ry’ubuhanga, umuyoboro wa 800MHz C, umuyoboro wa 900MHz G cyangwa izindi frequencies zitandukanye bigomba gusohoka icyarimwe. Hakoreshejwe combiner, seti ya sisitemu yo gukwirakwiza imbere ishobora gukora muri CDMA frequency band, GSM frequency band cyangwa izindi frequencies icyarimwe.

Urugero, muri sisitemu ya antene ya radiyo, ibimenyetso byinjiye n'ibisohoka by'imirongo itandukanye ya frequencies (nka 145mhz na 435mhz) bihuzwa binyuze muri combiner, hanyuma bigahuzwa na radiyo hifashishijwe feeder, ibyo bikaba bidakiza feeder gusa, ahubwo binarinda ingorane zo guhindura antene zitandukanye.

 

 

Eingaruka

Mu bikorwa by’ubuhanga, ni ngombwa guhuza umuyoboro wa 800MHz C na 900MHz G. Ukoresheje combiner, seti ya sisitemu yo gukwirakwiza imbere ishobora gukora muri CDMA band na GSM band icyarimwe. Urugero, muri sisitemu ya antene ya radiyo, ibimenyetso byinjiye n’ibisohoka by’imirongo itandukanye ya frequencies (nka 145mhz na 435mhz) bihuzwa binyuze muri combiner, hanyuma bigahuzwa na radiyo hakoreshejwe feeder, ibyo bikaba bidakiza gusa feeder, ahubwo binarinda ingorane zo guhindura antene zitandukanye..

 

Ibisobanuro by'ihame ry'ikigereranyo

Muri rusange, iyi mashini ihuza amakuru ikoreshwa ku mpera y’itumanaho. Inshingano yayo ni uguhuza ibimenyetso bibiri cyangwa byinshi bya RF byoherejwe bivuye mu byuma bitandukanye byohereza amakuru muri kimwe no kubyohereza ku bikoresho bya RF byoherejwe na antene, mu gihe birinda imikoranire hagati y’ibimenyetso bya buri cyambu.

Muri rusange, ibikoresho bihuza amashanyarazi bigira imiyoboro ibiri cyangwa myinshi yinjiye n'umuyoboro umwe gusa w'ibisohoka. Gutandukanya amashanyarazi ni ikimenyetso cy'ingenzi kigaragaza ubushobozi bw'ibimenyetso bibiri bidakora ku bindi. Muri rusange bisaba kurenza 20dB.

Ihuriro ry’ibiraro rya 3dB rifite imiyoboro ibiri y’inyongera n’imiyoboro ibiri y’inyongera, nk’uko bigaragara ku Ishusho ya 2. Rikunze gukoreshwa mu guhuza imirongo ibiri y’itumanaho ridafite insinga no kuyishyira muri antene cyangwa sisitemu yo gukwirakwiza. Iyo hakoreshejwe umuyoboro umwe gusa w’inyongera, undi muyoboro w’inyongera ugomba guhuzwa n’umutwaro wa 50W. Muri iki gihe, hari igihombo cya 3dB nyuma y’uko ikimenyetso gihujwe. Hari igihe imiyoboro yombi y’inyongera igomba gukoreshwa, bityo nta gihombo cya 3dB kibaho.

Huza uburyo bwo kwakira no kohereza telefoni igendanwa kuri antene imwe. Muri sisitemu ya GSM, kubera ko transceiver itari mu mwanya umwe, telefoni igendanwa ishobora gusiba duplexer kugira ngo ikure transceiver, hanyuma igakoresha gusa transceiver yoroshye kugira ngo ihuze ubutumwa bwo kohereza no kwakira muri antene imwe nta kubangamirana.

Ku bijyanye n'uruhererekane rw'amajwi, antene yakira ikimenyetso, ikinjira mu muyoboro wakira binyuze muri combiner, ikivanga n'ikimenyetso cya oscillator cyakiriwe (ni ukuvuga ikimenyetso cya VCO cyakiriwe cyakozwe na synthesizer ya frequency), gihindura ikimenyetso cya frequency yo hejuru kikaba ikimenyetso cya frequency yo hagati, hanyuma quadrature igahindura ikimenyetso kugira ngo ikore ibimenyetso bya I na Q byakiriwe; Hanyuma hakorwa demodulation ya GMSK (Gaussian filter minimum frequency shift keying) kugira ngo ikimenyetso cya analog kibe ikimenyetso cya digitale, hanyuma cyoherezwe mu gice gitunganya baseband.

Ku bijyanye n'uruhererekane rw'itumanaho, igice cy'umurongo w'ifatizo cyohereza amakuru ya TDMA frame (hamwe n'igipimo cya 270.833kbit / s) kugira ngo hakorwe modulation ya GSMK kugira ngo habeho ibimenyetso bya transmission I na Q, hanyuma byoherezwa kuri transformer yohereza kugira ngo ihindurwe kuri band ya transmission frequency. Nyuma yo kongera imbaraga, transmitter yohereza ikoresheje antene.

Iyi frequensizer itanga ikimenyetso cya oscillator cyo mu gace gikenewe kugira ngo ihindure frequensi ku gice cyohereza no kwakira, kandi ikoresha ikoranabuhanga rya phase-locked loop kugira ngo ihamye frequensi. Ibona frequensi ituruka ku cyerekezo cy'isaha.

Umuyoboro w'isaha muri rusange ni isaha ya 13mhz. Ku ruhande rumwe, itanga ishusho y'isaha yo gukoresha umurongo wa frequency synthesis hamwe n'isaha ikora yo gukoresha umurongo wa logic.

Icyiciro cy'ingenzi

Imashini ihuza inshuro ebyiri

① JCDUP-8019

GSM na 3G bihuza inshuro ebyiri ni igikoresho gifite uburyo bwo kwinjira n'ubusohoka bwa kimwe. Ikimenyetso cya GSM (885-960mhz) gishobora guhuzwa n'ikimenyetso cya 3G (1920-2170MHz).

② JCDUP-8028

DCS na 3G dual frequency combiner ni igikoresho gifite ikoranabuhanga rya "two in" na "one out". Ikimenyetso cya DCS (1710-1880mhz) gishobora guhuzwa n'ikimenyetso cya 3G (1920-2170MHz).

③ JCDUP-8026B

(TETRA / iden / CDMA / GSM) & (DCS / PHS / 3G / WLAN) ihuza frequency ebyiri ni igikoresho gifite ikoranabuhanga rya "two in" na "one out". Ihuriro rimwe rikubiyemo frequency ya tetra / iden, CDMA na GSM system (800-960MHz), kandi rishobora kwinjiza tetra / iden, CDMA, GSM cyangwa uruvange rwabyo; Irindi huriro rikubiyemo frequency ya DCS, PHS, 3G na WLAN system (1710-2500mhz), kandi rishobora kwinjiza DCS, PHS, 3G, WLAN cyangwa uruvange rwabyo.

④ JCDUP-8022

(CDMA / GSM / DCS / 3G) na WLAN dual frequency combiner ni igikoresho gifite ikoranabuhanga rya "two in" na "one out". Umuyoboro umwe utwikira CDMA, GSM, DCS na 3G system frequency band (824-960 / 1710-2170mhz), kandi ushobora kwinjiza CDMA, GSM, DCS, 3G cyangwa ikindi kintu cyose kivanze; Undi muyoboro utwikira umuyoboro wa WLAN system frequency band (2400-2500mhz) kandi ushobora kwinjiza ibimenyetso bya WLAN system.

Imashini ihuza inshuro eshatu

① JCDUP-8024 / JCDUP-8024B

GSM & DCS & 3G three frequency combiner ni igikoresho gifite ikoranabuhanga rya "three in" na "one out". Ibimenyetso bya GSM (885-960mhz), DCS (1710-1880mhz) na 3G (1920-2170MHz) birashobora guhuzwa.

② JCDUP-8018

GSM & 3G & WLAN three frequency combiner ni igikoresho gifite ikoranabuhanga rya "three in" na "one out". Ibimenyetso bya GSM (885-960mhz), 3G (1920-2170MHz) na WLAN (2400-2500mhz) birashobora guhuzwa.

Imashini ihuza inshuro enye

① JCDUP-8031

GSM & DCS & 3G & WLAN four frequency combiner ni igikoresho gifite umurongo umwe usohokamo inshuro enye. GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) na WLAN (2400-2483.5mhz) ibimenyetso bine bishobora guhuzwa.

Byongeye kandi, mu ikoreshwa rya combiner, ni ngombwa kumenya ko uburyo bwo gutanga ibimenyetso kuri sitasiyo y'ibanze cyangwa repeater budafite umugozi, kandi isoko yabyo ni wide spectrum. Kubwibyo, umugozi muto ukenewe mu bihe bimwe na bimwe kugira ngo ikimenyetso kibe cyiza; Uburyo bwo gutanga ibimenyetso kuri combiner ni cable, kandi ikimenyetso gifatwa mu buryo butaziguye, ari cyo kimenyetso cya spectrum nto. Urugero, CDMA / GSM channel ya combiner jcdup-8026b ifite ubugari bwa channel ya 800-960MHz. Iyo ugeze kuri GSM carrier frequency, kubera ko isoko ari ikimenyetso cya carrier frequency, uburyo bwo gutanga amakuru ni cable, kandi hari iki kimenyetso cya carrier frequency gusa muri channel nta zindi signal zibangamira. Kubwibyo, imiterere ya channel ya combiner irashoboka mu buryo bufatika.

Dushobora kandi guhindura ibice bya rf passive hakurikijwe ibyo ukeneye. Ushobora kwinjira ku ipaji yo guhindura kugira ngo utange ibisobanuro ukeneye.
