Iindaba

I-Sichuan Keenlion Microwave Technology Yasekwa ngo-2004, iSichuan Keenlion Mircrowave techenology CO., Ltd. ngumenzi okhokelayo wamacandelo ePassive Mircrowave eSichuan Chengdu, eChina.

Sinikezela ngamacandelo e-mirrowave asebenza kakhulu kunye neenkonzo ezinxulumene noko kwizicelo ze-microwave ekhaya naphesheya. Iimveliso azibizi kakhulu, kubandakanya ukwahlula amandla okwahlukeneyo, ii-couplers ezikhokelayo, izihluzi, izihlanganisi, ii-duplexers, iikhomponenti ezenziwe ngokwezifiso, i-isolator kunye neesetyhula. Iimveliso zethu ziyilelwe ngokukodwa iimeko ezahlukeneyo ezingqongileyo kunye namaqondo obushushu. Iinkcukacha zinokuqulunqwa ngokweemfuno zabathengi kwaye zisebenza kuzo zonke iibhendi eziqhelekileyo kunye nezidumileyo ezinamaza ohlukeneyo ukusuka kwi-DC ukuya kwi-50GHz.

Duplexer

I-duplexer sesona sixhobo siphambili sesixhobo sokusebenza esiphindwe kabini sangaphandle kunye nesikhululo sokuhambisa, oko kukwahlula imiqondiso yokuhambisa kunye nokwamkela, ukuqinisekisa ukuba okufunyenweyo kunye nokuhanjiswa kunokusebenza ngokufanelekileyo. Iqulathe iiseti ezimbini zezihluzi ze-bandpass zefrikhwensi ezahlukeneyo, ukuphepha imiqondiso yokuhambisa yendawo kumamkeli.

Iduplexerisetyenziselwa ukuhambisa unxibelelwano kunye nokusebenza endle njengeNqaba engajongwanga, yona ngokwayo imisela indawo yokusetyenziswa kwayo kunye neemeko zokusebenza.

Okokuqala, sinethemba lokuba i-duplexer incinci, ilula. Okwangoku, ngenxa yomthamo we-duplexer kunye neminye imiba yobugcisa, i-duplexer yeerediyo eziphathwayo azikabikwa. Kodwa ngenxa yesithuba esinokubonelelwa kwii-radiotelers zeemoto, iimoto, njl.

Okwesibini, i-duplexer kufuneka kube lula ukuyifaka, ngakumbi xa ufaka ezinye ii-duplexer kunye neerediyo. Kufuneka yomelele, ithembeke, ibambene, ikwazi ukumelana neempembelelo ezithile kunye nokungcangcazela, ngakumbi umnxeba ongenazingcingo kwindawo ethile yejografi. Siyazi ukuba i-duplexer yangoku isasazwa kakhulu iparameters ukumisela iimfuno ze-frequency yayo yokusebenza. Ukuba ulwakhiwo lwe-duplexer alulungelelaniswa, kunokwenzeka ukuba kubangele ukuba ifowuni engenazingcingo ithobeke, nokuba ngummkeli ovuthayo. Kancinci ibaluleke kakhulu. Ngaphaya koko, iluncedo ngakumbi njengesikhululo sokufuduka esirhabaxa ngakumbi, esifuna ukuba i-duplexer iqinisekise umgangatho wonxibelelwano ngaphakathi koluhlu lobushushu obusebenzayo. Ngokuqhelekileyo, i-duplex kufuneka ibe nomgangatho ocacileyo wokushisa osebenzayo kwaye ibe nezikhombisi zozinzo lokutshintsha kweqondo lokushisa ukuhlangabezana neemfuno zokusetyenziswa komatshini wonke.

 

 

Intshayelelo

I-duplex eqhelekileyo inezihluzo ezintandathu ezinganyangekiyo, iresonant nganye iyahanjiswa kwaye ifunyenwe rhoqo. Isihluzi sokugqibela esifumanayo siphinda sisasaze i-frequency yokuhambisa kwaye sithintele ummkeli wentambo yamandla osasazo, kwaye isihluzi sokugqibela sokuhambisa siphinda sisasaze ulwamkelo. Ezinye ii-duplexers azibhalwanga kwaye zifunyenwe kuphela Phantsi kunye ne-HIGH kuphela, njenge-doublock Phantsi = 450, ephezulu = 460, ebonisa ukuba isiphelo se-LOW sinokujoyina i-terminal ye-450 ye-mega receiver HIGH ukujoyina i-460 megabyte transmitter, okanye isiphelo esisezantsi siqhagamshelwe kwi-450 megabyte transmitter. I-terminal HIGH iqhagamshelwe kwi-460 ye-megabyte receiver, kwaye i-transmission kunye ne-reception frequency inokuguqulwa, kodwa i-frequency transmit 460 ayinakuqhagamshelwa kwi-duplexer 450 megabytes ukuphepha umonakalo kwisikhululo kunye ne-duplexer.

 

 

Khetha

I-duplexer kufuneka ilungiselelwe ngokwamaza osasazo erediyo. I-400 megabye frequency difference 10 MHz duplexer work bandwidth inokuqinisekisa ukuba i-isolation imalunga ne-90 dB, kwaye i-frequency point eyodwa ine-single yokusebenza yodwa ye-120 dB. Xa i-frequency yokusetyenziswa idlula ububanzi be-duplexer eluhlaza, ukuhanjiswa kunye nokwamkeleka kokwahlula kuya kunyuka ngokukhawuleza, kwaye isiphaluka esifumanayo asisebenzi kakuhle ngenxa yobuntununtunu besahlulo esigqithisiweyo. I-terminal ye-radiographing ye-Amateur i-terminal U ifumana ngokubanzi i-5 megabytes Hz, i-duplexer esetyenzisiweyo yi-narrowband design, eqinisekisa ukuba ukuhlukaniswa akuthotywanga, kodwa i-bandwidth esebenzayo iyancipha, kwaye yi-100 kHz. Ukuziqhelanisa kubonakalise ukuba ukusetyenziswa kwee-duplexers kungcono kunokusebenzisa i-eriyali ezimbini.

 

Sisenokwenza ngokwezifiso amalungu e-rf passive ngokweemfuno zakho. Ungangenisa iphepha lokulungiselela ukubonelela ngeenkcukacha ozifunayo.
