Tekinoroji yeSichuan Keenlion Microwave——Musanganiswa

Sichuan Keenlion Microwave Technology Yakavambwa muna 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ndiyo inotungamira mukugadzira zvikamu zvePassive Mircrowave muSichuan Chengdu, China.

Tinopa zvikamu zve mirrowave zvinoshanda zvakanyanya uye masevhisi akafanana ekushandisa muma microwave kumba nekune dzimwe nyika. Zvigadzirwa izvi zvinodhura zvishoma, zvinosanganisira zvinoparadzanisa simba zvakasiyana-siyana, zvinobatanidza ma directional couplers, ma filters, zvinosanganisa ma combiners, ma duplexers, zvikamu zve passive zvakagadzirwa, zvinoparadzanisa ma isolators uye zvinotenderera magetsi. Zvigadzirwa zvedu zvakagadzirirwa nzvimbo dzakasiyana-siyana dzakanyanya uye tembiricha. Magadzirirwo anogona kugadzirwa zvichienderana nezvinodiwa nevatengi uye anoshanda kune ese ma standard uye popular frequency bands ane bandwidths dzakasiyana kubva kuDC kusvika ku50GHz.

Musanganiswa

Muhurongwa hwekutaurirana nenharembozha husina waya, basa guru remusanganisi nderekubatanidza masaini ekupinda emabhandi akawanda uye kuaburitsa kune imwe nzira yekugovera yemukati.

Mukushandiswa kweinjiniya, network ye800MHz C, network ye900MHz G kana mamwe ma frequency akasiyana anofanirwa kuburitswa panguva imwe chete. Uchishandisa combiner, seti ye indoor distribution system inogona kushanda muCDMA frequency band, GSM frequency band kana mamwe ma frequency band panguva imwe chete.

Semuenzaniso, muhurongwa hweredhiyo antenna, masaini ekupinda nekubuda emabhandi akasiyana-siyana (akadai se145mhz ne435mhz) anosanganiswa kuburikidza nemuchina wekubatanidza, uye obva abatanidzwa nechiteshi cheredhiyo nemudziyo wekudyara, izvo zvisingangobatsiri chete mudziyo wekudyara, asiwo zvinodzivirira matambudziko ekuchinja maantenna akasiyana.

 

 

Esimba

Mukushandiswa kwemainjiniya, zvinodikanwa kusanganisa network ye800MHz C uye network ye900MHz G. Uchishandisa combiner, seti yesystem yekugovera yemukati inogona kushanda muCDMA band neGSM band panguva imwe chete. Semuenzaniso, mune system yeradio antenna, masaini ekupinda nekubuda emabhendi akasiyana-siyana (akadai se145mhz ne435mhz) anosanganiswa kuburikidza necombiner, uye obva abatanidzwa neredhiyo station ne feeder, izvo zvisingangobatsiri feeder chete, asiwo zvinodzivirira matambudziko ekuchinja maantenna akasiyana..

 

Tsananguro yemuenzaniso wekutanga

Musanganiswa unowanzo shandiswa pamagumo ekutumira. Basa rawo nderekubatanidza masaini maviri kana anopfuura eRF anotumirwa kubva kumatransmitter akasiyana kuita rimwe chete uye kuatumira kumidziyo yeRF inotumirwa neantenna, uku uchidzivirira kusangana pakati pemasaini echiteshi chimwe nechimwe.

Macombiners anowanzova nema input ports maviri kana anopfuura uye output port imwe chete. Port isolation inhamba yakakosha yekutsanangura kugona kwemasaini maviri kusabatana. Kazhinji inofanirwa kunge inopfuura 20dB.

Musanganiswa we3dB bridge une ma "input ports" maviri uye ma "output ports" maviri, sezvakaratidzwa muMufananidzo 2. Unoshandiswa kazhinji kugadzira ma "wireless carrier frequency" maviri uye kuaisa mu "antenna" kana "distribution system". Kana pakashandiswa "output port" imwe chete, imwe "output port" inofanira kubatanidzwa kune "50W load". Panguva ino, pane kurasikirwa kwe3dB mushure mekunge chiratidzo chabatanidzwa. Dzimwe nguva ma "output ports" ese maviri anofanira kushandiswa, saka hapana "load" uye hapana "3dB loss".

Sanganisa kugamuchira nekutumira kwefoni yechiratidzo kune antenna imwe chete. MuGSM system, nekuti transceiver haisi panguva imwe chete, foni inogona kusiya duplexer kuti iparadzanise transceiver, uye ingoshandisa transceiver combiner iri nyore kubatanidza kutumira nekugamuchira masaini mune antenna imwe chete pasina kukanganisana.

Kune dunhu rinogamuchira, antenna inogamuchira chiratidzo, inopinda muchiteshi chinogamuchira kuburikidza nemusanganisi, inosanganisa nechiratidzo cheoscillator chemunharaunda chinogamuchirwa (kureva chiratidzo cheVCO chinogamuchirwa chinogadzirwa ne frequency synthesizer), inoshandura chiratidzo che high-frequency kuita chiratidzo chepakati pe frequency, uye yobva yabvisa chiratidzo che quadrature kuti igadzire zviratidzo zve I ne Q zvinogamuchirwa; Zvadaro GMSK (Gaussian filter minimum frequency shift keying) demodulation inoitirwa kushandura chiratidzo che analog kuita chiratidzo che digital, uye yozotumirwa ku baseband processing unit.

Padanho rekutumira, chikamu chebaseband chinotumira data reTDMA frame (rine mwero we270.833kbit / s) reGMK modulation kuti rigadzire masaini ekutumira I neQ, ayo anozotumirwa kune transmission up converter kuti ikwanise kuchinja kubhendi rekufambisa. Mushure mekuwedzera simba, transmitter inoitumira neantenna.

Iyo frequency synthesizer inopa chiratidzo che local oscillator chinodiwa pakushandura frequency ye transmitter ne receiving unit, uye inoshandisa phase-locked loop tekinoroji kudzikamisa frequency. Inowana frequency reference kubva ku clock reference circuit.

Dunhu rekutarisa wachi rinowanzova wachi ye13mhz. Kune rumwe rutivi, rinopa dudziro yewachi yedunhu rekugadzira frequency uye wachi inoshanda yedunhu relogic.

Kurongwa kukuru

Musanganiswa wekaviri-frequency

① JCDUP-8019

Musanganiswa weGSM ne3G une mafrequency maviri anopinda uye anobuda. Chiratidzo cheGSM (885-960mhz) chinogona kusanganiswa nechiratidzo che3G (1920-2170MHz).

② JCDUP-8028

Musanganiswa wemafrequency mana

① JCDUP-8031

GSM & DCS & 3G & WLAN four frequency combiner chishandiso chine ma "four in one out". GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) uye WLAN (2400-2483.5mhz) ma "frequency signaler" mana anogona kubatanidzwa.

Pamusoro pezvo, pakushandisa combiner, zvinofanira kucherechedzwa kuti nzira yekudyisa masaini yebase station kana repeater haina waya, uye kwainobva i wide spectrum. Saka, passband yakamanikana inodiwa mune dzimwe nguva kuti ive nechokwadi chekuti chiratidzo chakachena; Nzira yekudyisa masaini ye combiner i cable, uye chiratidzo chinotorwa zvakananga kubva kunobva, inova chiratidzo chakamanikana. Semuenzaniso, CDMA / GSM channel ye combiner jcdup-8026b ine upamhi hwechiteshi che 800-960MHz. Paunenge uchisvika pachiratidzo cheGSM carrier frequency, nekuti tsime racho i carrier frequency signal, nzira yekudyisa i cable, uye pane chiratidzo ichi che carrier frequency mu channel pasina mamwe ma interference signals. Nokudaro, dhizaini ye carrier frequency yakamanikana inogoneka mukushanda kwayo.

Tinogonawo kugadzirisa zvikamu zveRF passive zvinoenderana nezvamunoda. Munogona kupinda papeji rekugadzirisa kuti mupe zvinodiwa zvamunoda.
