Itekhnoloji yeMicrowave yaseSichuan Keenlion——Umdibanisi

Itekhnoloji yeMicrowave yaseSichuan Keenlion Yasekwa ngo-2004, iSichuan Keenlion Mircrowave techenology CO., Ltd. ngumenzi ophambili wezixhobo zePassive Mircrowave eSichuan Chengdu, eTshayina.

Sinikezela ngezixhobo ze-mirrowave ezisebenza kakuhle kunye neenkonzo ezinxulumene nazo kwii-microwave ekhaya nakwamanye amazwe. Ezi mveliso zixabisa kancinci, kuquka izixhobo ezahlukeneyo zokwahlula amandla, izixhobo zokudibanisa ezikhokelayo, izihluzi, izixhobo zokudibanisa, izixhobo zokudibanisa, izixhobo zokudibanisa, izixhobo ezizenzekelayo ezingasebenziyo, izixhobo zokwahlulahlula kunye nezixhobo zokujikeleza. Iimveliso zethu zenzelwe ngokukodwa iimeko ezahlukeneyo zobushushu kunye namaqondo obushushu agqithisileyo. Iinkcukacha zinokwenziwa ngokweemfuno zabathengi kwaye ziyasebenza kuzo zonke iibhendi zefrikhwensi ezisemgangathweni nezithandwayo ezineebhendi ezahlukeneyo ukusuka kwi-DC ukuya kwi-50GHz.

Umdibanisi

Kwinkqubo yonxibelelwano olungenazingcingo, umsebenzi ophambili we-combiner kukudibanisa imiqondiso ye-input multi band kunye nokuyifaka kwinkqubo efanayo yokusasazwa kwangaphakathi.

Kwinkqubo yobunjineli, inethiwekhi ye-800MHz C, inethiwekhi ye-900MHz G okanye ezinye iifrequencies ezahlukeneyo kufuneka ziphume ngaxeshanye. Ukusebenzisa i-combiner, iseti yenkqubo yokusasaza yangaphakathi ingasebenza kwi-CDMA frequency band, i-GSM frequency band okanye ezinye iifrequencies ngaxeshanye.

Umzekelo, kwinkqubo ye-antenna yerediyo, imiqondiso yokufaka kunye neyokuphuma yeebhendi ezahlukeneyo zefrikhwensi (ezifana ne-145mhz kunye ne-435mhz) zidityaniswe nge-combiner, emva koko ziqhagamshelwe kwisikhululo serediyo nge-feeder, engagcini nje ngokusindisa i-feeder, kodwa ikwathintela ingxaki yokutshintsha ii-antenna ezahlukeneyo.

 

 

Eisiphumo

Kwizicelo zobunjineli, kuyimfuneko ukudibanisa inethiwekhi ye-800MHz C kunye nenethiwekhi ye-900MHz G. Ukusebenzisa i-combiner, iseti yenkqubo yokusasaza yangaphakathi ingasebenza kwi-CDMA band kunye ne-GSM band ngaxeshanye. Umzekelo, kwinkqubo ye-antenna yerediyo, imiqondiso yokufaka kunye neyokuphuma yeebhendi ezahlukeneyo ze-frequency (ezifana ne-145mhz kunye ne-435mhz) zidityaniswe nge-combiner, kwaye emva koko ziqhagamshelwe kwisikhululo serediyo nge-feeder, engagcini nje ngokusindisa i-feeder, kodwa ikwathintela ingxaki yokutshintsha ii-antenna ezahlukeneyo..

 

Inkcazo yomgaqo-siseko wofaniso

I-combiner isetyenziswa ngokubanzi kwisiphelo sokudlulisa. Umsebenzi wayo kukudibanisa imiqondiso ye-RF emibini okanye ngaphezulu ethunyelwa kwiitransmitter ezahlukeneyo ibe yinye ize izithumele kwizixhobo ze-RF ezithunyelwa yi-antenna, ngelixa kuthintelwa ukusebenzisana phakathi kwemiqondiso yezibuko ngalinye.

Ii-Combiners zihlala zinezibuko ezimbini okanye ngaphezulu zokufaka kunye nezibuko enye kuphela zokukhupha. Ukwahlulwa kwezibuko luphawu olubalulekileyo lokuchaza amandla ezibonakaliso ezimbini zokungachatshazeli omnye komnye. Ngokuqhelekileyo kufuneka ukuba ibe ngaphezu kwe-20dB.

I-3dB bridge combiner inee-input ports ezimbini kunye nee-output ports ezimbini, njengoko kubonisiwe kuMfanekiso 2. Isetyenziswa rhoqo ukwenza ii-wireless carrier frequencys ezimbini kwaye ziyongeze kwi-antenna okanye kwinkqubo yokusasaza. Ukuba kusetyenziswa i-output port enye kuphela, enye i-output port kufuneka iqhagamshelwe kumthwalo we-50W. Ngeli xesha, kukho ilahleko ye-3dB emva kokuba isignali idityanisiwe. Ngamanye amaxesha kufuneka kusetyenziswe zombini ii-output ports, ngoko ke akukho mthwalo kwaye akukho lahleko ye-3dB.

Dibanisa ukwamkela nokuthumela kwefowuni yesignali kwi-antenna enye. Kwinkqubo ye-GSM, kuba i-transceiver ayikho kwindawo enye yexesha, ifowuni ephathwayo inokushiya i-duplexer ukuze ihlukanise i-transceiver, kwaye isebenzise kuphela i-transceiver combiner elula ukudibanisa imiqondiso yokuthumela neyokwamkela kwi-antenna enye ngaphandle kokuphazamisana.

Kwisekethe yokwamkela, i-antenna ifumana isignali, ingena kwitshaneli yokwamkela nge-combiner, ixube nesignali ye-oscillator yendawo efunyenweyo (oko kukuthi isignali ye-VCO efunyenweyo eyenziwe yi-frequency synthesizer), itshintsha isignali ye-high-frequency ibe yisignali ye-frequency ephakathi, ize emva koko i-quadrature idibanise isignali ukuvelisa imiqondiso ye-I kunye ne-Q efunyenweyo; Emva koko i-GMSK (Gaussian filter minimum frequency shift keying) idemodulation iguqule isignali ye-analog ibe yisignali yedijithali, ize ithunyelwe kwiyunithi yokucubungula i-baseband.

Kwisekethe yokudlulisa, inxalenye yebhendi yesiseko ithumela umjelo wedatha yesakhelo seTDMA (ngesantya se-270.833kbit / s) kwimodulation ye-GSMK ukwenza imiqondiso yokudlulisa i-I kunye ne-Q, ezithunyelwa kwi-transmission up converter ukuze ziguqulwe kwibhendi yefrikhwensi yokudlulisa. Emva kokwandiswa kwamandla, i-transmitter iyithumela nge-antenna.

I-frequency synthesizer inika isignali ye-oscillator yendawo efunekayo ekuguquleni i-frequency yeyunithi yokudlulisa neyokwamkela, kwaye isebenzisa iteknoloji ye-phase-locked loop ukuzinzisa i-frequency. Ifumana i-frequency reference kwi-clock reference circuit.

Isekethe yesalathiso sewotshi ngokubanzi yiwotshi ye-13mhz. Kwelinye icala, ibonelela ngesalathiso sewotshi yesekethe ye-frequency synthesis kunye newotshi esebenzayo yesekethe ye-logic.

Ukongeza, xa kusetyenziswa i-combiner, kufuneka kuqatshelwe ukuba indlela yokutya isignali yesikhululo sesiseko okanye i-repeater ayinazingcingo, kwaye umthombo wayo yi-wide spectrum. Ke ngoko, i-passband encinci iyafuneka kwezinye iimeko ukuqinisekisa ubunyulu besignali; Indlela yokutya isignali ye-combiner yintambo, kwaye isignali ithathwa ngqo kumthombo, ongumqondiso we-spectrum omncinci. Umzekelo, itshaneli ye-CDMA / GSM ye-combiner jcdup-8026b inobubanzi betshaneli ye-800-960MHz. Xa ufikelela kwisignali ye-frequency carrier carrier, kuba umthombo yisignali ye-frequency carrier, indlela yokutya yintambo, kwaye kukho kuphela le signali ye-frequency carrier kwitshaneli ngaphandle kwezinye iimpawu zokuphazamiseka. Ke ngoko, uyilo lwetshaneli ebanzi ye-combiner lunokwenzeka kwisicelo esisebenzayo.
