Sichuan Keenlion Ikoranabuhanga rya Microwave --—Combiner

Ikoranabuhanga rya Sichuan Keenlion Microwave Yashinzwe mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ni iya mbere mu gukora ibice bya Passive Mircrowave i Sichuan Chengdu, mu Bushinwa.

Dutanga imikorere-yimikorere ya mirrowave hamwe na serivisi zijyanye na porogaramu ya microwave murugo no mumahanga. Ibicuruzwa birahenze cyane, harimo gutandukanya imbaraga zitandukanye, guhuza icyerekezo, gushungura, guhuza, duplexers, ibikoresho byabigenewe byabigenewe, kwigunga no kuzenguruka. Ibicuruzwa byacu byateguwe byumwihariko kubidukikije bikabije nubushyuhe. Ibisobanuro birashobora gutegurwa ukurikije ibyo umukiriya asabwa kandi birakurikizwa kumurongo wose usanzwe kandi uzwi cyane hamwe numuyoboro utandukanye kuva DC kugeza 50GHz.

Combiner

Muri sisitemu yo gutumanaho itagendanwa idafite umugozi, umurimo wingenzi wa combiner ni uguhuza ibyinjijwe byinshi byerekana ibimenyetso hanyuma ukabisohora muri sisitemu imwe yo gukwirakwiza mu nzu

Mubikorwa byubwubatsi, umuyoboro wa 800MHz C, umuyoboro wa 900MHz G cyangwa indi mirongo itandukanye igomba gusohoka icyarimwe. Ukoresheje imashini, sisitemu yo gukwirakwiza imbere murugo irashobora gukora mumurongo wa CDMA yumurongo, GSM yumurongo wa bande cyangwa indi mirongo ya bande icyarimwe.

Kurugero, muri sisitemu ya antenne ya radio, ibyinjira nibisohoka byerekana imirongo myinshi itandukanye (nka 145mhz na 435mhz) byahujwe binyuze mumashanyarazi, hanyuma bigahuzwa na radio hamwe na federasiyo, ntabwo ikiza ibiryo gusa, ahubwo ikanirinda ikibazo cyo guhindura antene zitandukanye.

 

 

Ebyuzuye

Mubikorwa byubwubatsi, birakenewe guhuza umuyoboro wa 800MHz C numuyoboro wa 900MHz G. Ukoresheje imashini, sisitemu yo gukwirakwiza imbere murugo irashobora gukora mugice cya CDMA hamwe na GSM band icyarimwe. Urundi rugero, muri sisitemu ya antenna ya radio, ibyinjira nibisohoka byerekana imirongo myinshi itandukanye (nka 145mhz na 435mhz) byahujwe binyuze mumashanyarazi, hanyuma bigahuzwa na radio hamwe na federasiyo, ntabwo ikiza ibiryo gusa, ahubwo ikanirinda ikibazo cyo guhindura antene zitandukanye..

 

Ibisobanuro ngenderwaho bisobanura

Imashini ikoreshwa muburyo bwo kohereza. Igikorwa cyayo ni uguhuza ibimenyetso bibiri cyangwa byinshi bya RF byoherejwe biva mumashanyarazi atandukanye hanyuma ukabyohereza mubikoresho bya RF byoherejwe na antene, mugihe wirinze imikoranire hagati yibimenyetso bya buri cyambu.

Gukomatanya muri rusange bifite ibyambu bibiri cyangwa byinshi byinjira hamwe nicyambu kimwe gisohoka. Kwigunga kw'icyambu ni indangagaciro y'ingenzi yo gusobanura ubushobozi bw'ibimenyetso bibiri bitagira ingaruka kuri mugenzi we. Mubisanzwe birasabwa kurenza 20dB.

Ikiraro cya 3dB gifite ibyambu bibiri byinjira hamwe nibyambu bibiri bisohoka, nkuko bigaragara ku gishushanyo cya 2. Bikunze gukoreshwa muguhuza inshuro ebyiri zitwara umugozi utabigenewe no kubigaburira muri antenne cyangwa sisitemu yo gukwirakwiza. Niba icyambu kimwe gisohoka gusa, ikindi gisohoka icyambu gikeneye guhuzwa numutwaro wa 50W. Muri iki gihe, hari igihombo cya 3dB nyuma yikimenyetso hamwe. Rimwe na rimwe, ibyambu byombi bisohoka bigomba gukoreshwa, nta mutwaro uhari kandi nta gihombo cya 3dB.

Huza kwakira no kohereza ibimenyetso bya terefone igendanwa kuri antene imwe. Muri sisitemu ya GSM, kubera ko transceiver itari mugihe kimwe, terefone igendanwa irashobora gusiba duplexer yo gutandukanya transceiver, kandi igakoresha gusa imashini yoroheje yo guhuza guhuza no kohereza ibimenyetso muri antenne imwe itabangamiye undi.

Kumuzunguruko wakira, antenne yakira ibimenyetso, yinjira mumiyoboro yakira ikoresheje kombineri, ivanga nikimenyetso cya oscillator yakiriwe (ni ukuvuga ikimenyetso cya VCO cyakiriwe na synthesizer ya frequency), gihindura ibimenyetso byumuvuduko mwinshi mubimenyetso biciriritse, hanyuma quadrature ikuraho ikimenyetso kugirango itange ibimenyetso byakiriwe I na Q; Hanyuma GMSK (Gaussian filter byibuze ya shift ya urufunguzo) demodulation ikorwa kugirango ihindure ibimenyetso bisa mubimenyetso bya digitale, hanyuma byoherezwe murwego rwo gutunganya baseband.

Kumurongo wogukwirakwiza, igice cya baseband cyohereza amakuru ya TDMA ikadiri yamakuru (hamwe nigipimo cya 270.833kbit / s) kugirango modulisiyo ya GSMK ikore ibimenyetso byogukwirakwiza I na Q, hanyuma byoherezwa muburyo bwo guhinduranya ibintu kugirango bihindurwe kumurongo woherejwe. Nyuma yo kongera ingufu, transmitter yohereza hanze na antene.

Synthesizer ya frequence itanga ibimenyetso bya oscillator yaho ikenewe muguhindura inshuro kubice byohereza no kwakira, kandi ikoresha tekinoroji ya feri ifunze kugirango ihagarike inshuro. Irabona inshuro zivuye kumasaha yumuzunguruko.

Isaha yerekana isaha muri rusange ni 13mhz. Ku ruhande rumwe, itanga isaha yerekanwe kumirongo yumuzunguruko hamwe nisaha yakazi ya logic circuit.

Ibyiciro byingenzi

Imirongo ibiri ikomatanya

① JCDUP-8019

GSM & 3G inshuro ebyiri ikomatanya ni ebyiri muri kimwe nigikoresho kimwe. Ikimenyetso cya GSM (885-960mhz) gishobora guhuzwa nikimenyetso cya 3G (1920-2170MHz).

② JCDUP-8028

DCS & 3G ikomatanya inshuro ebyiri ni ebyiri muri kimwe hamwe nigikoresho kimwe. Ikimenyetso cya DCS (1710-1880mhz) gishobora guhuzwa nikimenyetso cya 3G (1920-2170MHz).

③ JCDUP-8026B

. (TETRA / iden / CDMA / GSM) & Icyambu kimwe gikubiyemo tetra / iden, CDMA na GSM sisitemu yumurongo (800-960MHz), kandi irashobora kwinjiza tetra / iden, CDMA, GSM cyangwa guhuza kwayo; Ikindi cyambu gikubiyemo umurongo wa DCS, PHS, 3G na sisitemu ya WLAN (1710-2500mhz), kandi irashobora kwinjiza DCS, PHS, 3G, WLAN cyangwa guhuza kwabo.

④ JCDUP-8022

. Icyambu kimwe gikubiyemo CDMA, GSM, DCS na 3G sisitemu yumurongo wa sisitemu (824-960 / 1710-2170mhz), kandi irashobora kwinjiza CDMA, GSM, DCS, 3G cyangwa guhuza kwayo; Ikindi cyambu gikubiyemo umurongo wa WLAN ya sisitemu (2400-2500mhz) kandi irashobora kwinjiza ibimenyetso bya sisitemu ya WLAN.

Imirongo itatu ikomatanya

① JCDUP-8024 / JCDUP-8024B

GSM & DCS & 3G inshuro eshatu zikomatanya ni eshatu muri kimwe nigikoresho cyo hanze. Ibimenyetso bya GSM (885-960mhz), DCS (1710-1880mhz) na 3G (1920-2170MHz) bishobora guhuzwa.

② JCDUP-8018

GSM & 3G & WLAN inshuro eshatu zikomatanya ni eshatu muri kimwe nigikoresho cyo hanze. Ibimenyetso bya GSM (885-960mhz), 3G (1920-2170MHz) na WLAN (2400-2500mhz) bishobora guhuzwa.

Imirongo ine yumurongo

① JCDUP-8031

GSM & DCS & 3G & WLAN inshuro enye zikomatanya ni enye mubikoresho bimwe. GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) na WLAN (2400-2483.5mhz) ibimenyetso bine byinshyi birashobora guhuzwa.

Mubyongeyeho, mugukoresha imashini ikomatanya, twakagombye kumenya ko uburyo bwo kugaburira ibimenyetso bya sitasiyo fatizo cyangwa gusubiramo bitagira umugozi, kandi inkomoko yabyo ni nini cyane. Kubwibyo, umuhanda muto urasabwa mubihe bimwe kugirango umenye neza ibimenyetso; Uburyo bwo kugaburira uburyo bwo guhuza ni umugozi, kandi ibimenyetso byafashwe biturutse ku isoko, ni ikimenyetso kigufi. Kurugero, umuyoboro wa CDMA / GSM wa combiner jcdup-8026b ufite umuyoboro wa 800-960MHz. Iyo winjiye mubimenyetso bya GSM yikurikiranabikorwa, kubera ko isoko ari ikimenyetso cyitwara ryitwara, uburyo bwo kugaburira ni insinga, kandi hariho iki kimenyetso cyitwara gusa mumuyoboro nta bindi bimenyetso bibangamira. Kubwibyo, umuyoboro mugari wa combiner birashoboka mubikorwa bifatika.

Turashobora kandi gutegekanya ibice bya rf bikurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
