Izindaba

Ubuchwepheshe be-Microwave beSichuan Keenlion Obusungulwe ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye ze-Passive Mircrowave eSichuan Chengdu, eShayina.

Sinikeza izingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezinhlelo zokusebenza ze-microwave ekhaya nakwamanye amazwe. Imikhiqizo ishibhile, kufaka phakathi i-power divider ehlukahlukene, ama-directional couplers, ama-filters, ama-combiners, ama-duplexers, izingxenye ezingasebenzi ezenziwe ngokwezifiso, ama-isolators nama-circulator. Imikhiqizo yethu yenzelwe ngokukhethekile izindawo ezahlukene kanye namazinga okushisa aphezulu. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi isebenza kuwo wonke ama-frequency band ajwayelekile nathandwayo anama-bandwidth ahlukahlukene kusukela ku-DC kuya ku-50GHz.

I-Duplexer

I-duplexer iyizesekeli eziyinhloko ze-workstation yangaphandle ephindwe kabili kanye nesiteshi sokudlulisa, okuwukuhlukanisa izimpawu zokudlulisa nezokwamukela, ukuqinisekisa ukuthi ezitholiwe nezithumelayo zingasebenza kahle. Iqukethe amasethi amabili ezihlungi ze-bandpass zamaza ahlukene, okugwema izimpawu zokudlulisa zendawo kumukeli.

Ii-duplexerisetshenziselwa ukuhambisa ukuxhumana nokusebenza endle njenge-Tower engagadiwe, okuyiyona enquma indawo yokusetshenziswa kwayo kanye nezimo zokusebenza.

Okokuqala, sithemba ukuthi i-duplexer incane, ilula. Njengamanje, ngenxa yobuningi be-duplexer nezinye izinkinga zobuchwepheshe, i-duplexer yama-radiot aphathwayo ayibikwanga. Kodwa ngesikhala esinganikezwa kuma-radiotelector ezimoto, ezimotweni, njll., futhi kukhona nezinkinga zocingo ezingenantambo kanye nokusatshalaliswa kokushisa, ukuze kuhlangatshezwane nezinye izinkomba zobuchwepheshe, i-duplexer miniaturization iyadingeka kakhulu.

Okwesibili, i-duplexer kumele ibe lula ukuyifaka, ikakhulukazi uma ufaka ama-duplexer nama-radiot athile. Kufanele ibe namandla, ithembeke, ibe ncane, kufanele ikwazi ukumelana nomthelela othile kanye nokudlidliza, ikakhulukazi ucingo olungenantambo lwendawo ethile. Siyazi ukuthi i-duplexer yamanje isakazwa kakhulu ukuze kunqunywe izidingo zemvamisa yokusebenza kwayo. Uma isakhiwo se-duplexer singalungiseki, kungenzeka ukuthi ucingo olungenantambo lonakale, ngisho nomamukeli ovuthayo. Okubaluleke kakhulu. Ngaphezu kwalokho, iwusizo kakhulu njengesiteshi sokufuduka esinzima kakhulu, okudinga ukuthi i-duplexer iqinisekise ikhwalithi yokuxhumana ngaphakathi kwebanga lokushisa lokusebenza elihambisanayo. Ngokuvamile, i-duplex kufanele ibe nebanga lokushisa lokusebenza elicacile futhi ibe nezinkomba zokuzinza kokushintsha kwezinga lokushisa ukuze ihlangabezane nezidingo zokusetshenziswa komshini wonke.

 

 

Isingeniso

I-duplex ejwayelekile iqukethe izihlungi eziyisithupha ezingamelani nemichilo, i-resonant ngayinye iyadluliswa futhi itholakele imvamisa. Isihlungi sokugcina sokwamukela sivuselela imvamisa yokudlulisa futhi sivimbele isamukeli sentambo yamandla okudlulisa, kanti isihlungi sokugcina sokudlulisa sivuselela imvamisa yokwamukela. Amanye ama-duplexer awanelebula futhi amukelwa kuphela Phansi kanye ne-HIGH, njenge-doublock Low = 450, high = 460, okubonisa ukuthi i-LOW end ingajoyina i-450 mega receiver HIGH terminal ukuze ijoyine i-460 megabyte transmitter, noma i-LOW end ixhunywe ku-450 megabyte transmitter. I-HIGH terminal ixhunywe ku-460 megabyte receiver, futhi imvamisa yokudlulisa kanye nokwamukela ingabuyiselwa emuva, kodwa imvamisa yokudlulisa engu-460 ayikwazi ukuxhunywa ku-duplexer engu-450 megabytes ukugwema ukulimala esiteshini kanye ne-duplexer.

 

 

Khetha

I-duplexer kufanele yenziwe ngokwezifiso ngokwemvamisa yokudlulisa umsakazo. Umehluko wemvamisa yama-megabye angu-400 I-bandwidth yomsebenzi we-duplexer engu-10 MHz ingaqinisekisa ukuthi ukuhlukaniswa kungama-dB angu-90, kanti iphuzu lemvamisa eyodwa linokwahlukana okukodwa kokusebenza okungu-120 dB. Uma imvamisa yokusetshenziswa idlula ububanzi obungavuthiwe be-duplexer, ukuhlukaniswa kokudlulisela nokwamukela kuzokhula kakhulu, futhi isekethe yokwamukela ayisebenzi kahle ngenxa yokuzwela kwengxenye edlulisiwe. Isigaba se-U se-terminal ye-radiographing yama-amateur ngokuvamile sithola ama-megabytes angu-5 Hz, i-duplexer esetshenziswayo iyidizayini ye-narrowband, eqinisekisa ukuthi ukuhlukaniswa akuncishisiwe, kodwa i-bandwidth yokusebenza incishisiwe, futhi ingu-100 kHz. Ukuzijwayeza kuye kwafakazela ukuthi ukusetshenziswa kwama-duplexer kungcono kunokusebenzisa ama-antenna amabili.

 

Singakwazi futhi ukwenza ngezifiso izingxenye ze-rf passive ngokwezidingo zakho. Ungangena ekhasini lokwenza ngezifiso ukuze unikeze imininingwane oyidingayo.
