Sichuan Keenlion Microwave Technology——Combiner

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

Isu tinopa yakakwirira-inoshanda mirrowave zvikamu uye zvinoenderana masevhisi ekushandisa microwave kumba nekune dzimwe nyika. Zvigadzirwa zvinodhura, zvinosanganisira akasiyana-siyana simba divider, anotungamira couplers, mafirita, masanganisi, duplexers, customized passive components, isolators uye circulators. Zvigadzirwa zvedu zvakagadzirirwa zvakanyanya kune akasiyana akanyanya nharaunda uye tembiricha. Tsanangudzo dzinogona kuumbwa zvinoenderana nezvinodiwa nevatengi uye dzinoshanda kune ese akajairwa uye akakurumbira mabhendi mabhendi ane akasiyana bandwidths kubva kuDC kusvika ku50GHz.

Combiner

Muiyo isina waya yenharembozha yekutaurirana sisitimu, basa guru remusanganisi nderekubatanidza iyo yekuisa akawanda mabhendi masaini uye nekuaburitsa kune imwecheteyo yemukati yekugovera system.

Mukushandiswa kweinjiniya, 800MHz C network, 900MHz G network kana mamwe ma frequency anofanirwa kuburitswa panguva imwe chete. Uchishandisa musanganiswa, seti yemukati yekugovera sisitimu inogona kushanda muCDMA frequency bhendi, GSM frequency bhendi kana mamwe ma frequency bhendi panguva imwe chete.

Semuyenzaniso, muredhiyo antenna system, iyo yekupinza uye yekubuda masaini emabhendi akati wandei akasiyana (akadai 145mhz uye 435mhz) anosanganiswa kuburikidza nemusanganisi, uyezve akabatana neredhiyo neredhiyo yekudyisa, iyo isingango chengetedza yekudyisa, asi zvakare inodzivirira dambudziko rekuchinja ma antenna akasiyana.

Mumashandisirwo einjiniya, zvinodikanwa kusanganisa 800MHz C network uye 900MHz G network. Uchishandisa musanganiswa, seti yemukati yekugovera sisitimu inogona kushanda muCDMA bhendi uye GSM bhendi panguva imwe chete. Kune mumwe muenzaniso, mune redhiyo antenna system, iyo yekupinza uye yekubuda masaini e akati wandei akasiyana ma frequency bhendi (akadai 145mhz uye 435mhz) anosanganiswa kuburikidza nemusanganisi, uyezve akabatana neredhiyo chiteshi neichinofudza, iyo isingango chengetedza yekudyisa, asi zvakare inodzivirira dambudziko rekuchinja ma antenna akasiyana..

 

Tsanangudzo yekufananidza nheyo

Musanganiswa unowanzo shandiswa pakupera kwekutumira. Basa rayo ndere kusanganisa maviri kana anopfuura masaini eRF anotumirwa kubva kune akasiyana transmitter mune imwe uye otumira kune RF zvishandiso zvinofambiswa neantenna, uku uchidzivirira kupindirana pakati pezvikwangwani zvechiteshi chega chega.

Combiners kazhinji ane maviri kana anopfuura ekuisa madoko uye imwe chete inobuda chiteshi. Port isolation indekisi yakakosha kutsanangura kugona kwemasaini maviri kuti asakanganisa mumwe nemumwe. Kazhinji inodiwa kuve inopfuura 20dB.

3dB bhiriji musanganisi ane zviteshi zviviri zvekupinza uye maviri anobuda zviteshi, sezvakaratidzwa muMufananidzo 2. Inowanzoshandiswa kugadzira maviri mawaya anotakura ma frequency uye kuapa mu antenna kana kugovera system. Kana chiteshi chimwe chete chinobuda chichishandiswa, imwe chiteshi chinobuda chinoda kubatanidzwa kune 50W mutoro. Panguva ino, pane 3dB kurasikirwa mushure mekunge chiratidzo chabatanidzwa. Dzimwe nguva zvese zvinobuda zviteshi zvinoda kushandiswa, saka hapana mutoro uye hapana kurasikirwa kwe3dB.

Sanganisa kugamuchira uye kutumira kwechiratidzo mbozha mbozha kune imwe antenna. Muchirongwa cheGSM, nekuti transceiver haisi mune imwe nguva slot, nhare mbozha inogona kusiya duplexer yekutsaura iyo transceiver, uye ingoshandisa iri nyore transceiver musanganisi kusanganisa kutumira uye kugamuchira masaini mune imwe antenna pasina kupindirana.

Kudunhu rekugamuchira, antenna inogamuchira chiratidzo, inopinda mugero rekugamuchira kuburikidza nemusanganisi, inosanganiswa neinogamuchirwa yemuno oscillator chiratidzo (kureva yakagamuchirwa VCO chiratidzo chinogadzirwa neiyo frequency synthesizer), inoshandura iyo yakakwira-frequency chiratidzo kuita yepakati frequency chiratidzo, uyezve quadrature inoderedza chiratidzo kuti ibudise yakagamuchirwa I uye Q masaini; Ipapo GMSK (Gaussian sefa shoma frequency shift keying) demodulation inoitwa kushandura iyo analog siginecha kuita chiratidzo chedhijitari, yozotumirwa kune baseband processing unit.

Yedunhu rekutapurirana, iyo baseband chikamu chinotumira iyo TDMA furemu data rwizi (ine chiyero che 270.833kbit / s) yeGSMK modulation kuti igadzire iyo yekufambisa I neQ masaini, ayo anozotumirwa kune inoendesa kumusoro inoshandura kuti igadzirise kune yekufambisa frequency bhendi. Mushure mekuwedzera kwesimba, iyo transmitter inoitumira kunze neantenna.

Iyo frequency synthesizer inopa yemuno oscillator siginecha inodiwa kuti frequency shanduko yekufambisa uye yekugamuchira unit, uye inoshandisa iyo-yakakiyiwa loop tekinoroji kudzikamisa frequency. Iyo inowana iyo frequency referensi kubva pawachi referensi redunhu.

Iyo wachi yereferensi yedunhu inowanzo 13mhz wachi. Kune rimwe divi, inopa wachi rengedzo yefrequency synthesis wedunhu uye yekushanda wachi ye logic wedunhu.

Main classification

Four frequency musanganisi

① JCDUP-8031

GSM & DCS & 3G & WLAN ina mafrequency musanganisi ndeye ina mune imwe kunze mudziyo. GSM (885-960mhz), DCS (1710-1880mhz), 3G (1920-2170MHz) uye WLAN (2400-2483.5mhz) zviratidzo zvina zvefrequency zvinogona kubatanidzwa.

Uye zvakare, mukushandiswa kwemusanganisi, zvinofanirwa kucherechedzwa kuti iyo chiratidzo chekudyisa modhi ye base chiteshi kana inodzokorora haina waya, uye kwainotangira yakafara spectrum. Naizvozvo, nhete passband inodiwa mune dzimwe nguva kuve nechokwadi kuchena kwechiratidzo; Chiratidzo chekudyisa modhi yemusanganisi tambo, uye chiratidzo chinotorwa zvakananga kubva kunobva, inova yakamanikana spectrum chiratidzo. Semuenzaniso, iyo CDMA / GSM chiteshi chemusanganisi jcdup-8026b ine chiteshi chakafara che800-960MHz. Paunenge uchiwana iyo GSM inotakura frequency sigi, nekuti sosi inotakura frequency sigi, nzira yekudyisa itambo, uye pane chete iyi inotakura frequency chiratidzo muchiteshi pasina mamwe masaini ekukanganisa. Naizvozvo, iyo yakafara chiteshi dhizaini yemubatanidzwa inogoneka mune inoshanda application.

Isu tinogona zvakare kugadzirisa iyo rf passive zvikamu zvinoenderana nezvaunoda. Iwe unogona kupinda peji rekugadzirisa kuti upe zvakatemwa zvaunoda.
