Izindaba

I-Sichuan Keenlion Microwave Technology Yasungulwa ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye zePassive Mircrowave eSichuan Chengdu, eChina.

Sihlinzeka ngezingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezicelo ze-microwave ekhaya naphesheya. Imikhiqizo ibiza kakhulu, kufaka phakathi isihlukanisi samandla ahlukahlukene, ama-couplers aqondisayo, izihlungi, izihlanganisi, ama-duplexer, izakhi ezenziwe ngokwezifiso zokungenzi lutho, ama-isolator nama-circulator. Imikhiqizo yethu iklanyelwe ngokukhethekile izindawo ezihlukahlukene eziyingozi kanye namazinga okushisa. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi iyasebenza kuwo wonke amabhendi amafrikhwensi ajwayelekile nadumile anomkhawulokudonsa ohlukahlukene ukusuka ku-DC kuye ku-50GHz.

I-Duplexer

I-duplexer iyizinsiza eziyinhloko zesiteshi sokusebenza esiphindwe kabili sangaphandle kanye nesiteshi sokudlulisa, okuwukuhlukanisa amasignali okudlulisa nokwamukela, ukuqinisekisa ukuthi okwamukelwe kanye nokudlulisa kungasebenza kahle. Iqukethe amasethi amabili ezihlungi ze-bandpass zamafrikhwensi ahlukene, ukugwema amasiginali wokudlulisa wasendaweni kumamukeli.

Ii-duplexerisetshenziselwa ukuhambisa ukuxhumana nokusebenza endle njengoMbhoshongo ongagadiwe, wona ngokwawo onquma indawo oyisebenzisayo nezimo zokusebenza.

Okokuqala, sithemba ukuthi i-duplexer incane, ilula. Njengamanje, ngenxa yomthamo we-duplexer nezinye izinkinga zobuchwepheshe, i-duplexer yamarediyo aphathwayo ayikabikwa. Kodwa ngenxa yesikhala esinganikezwa kuma-radiotelers emoto, izimoto, njll., futhi kukhona nezinkinga zocingo ezingenazintambo kanye nezinkinga zokushisa ukushisa, ukuze kuhlangatshezwane nezinye izinkomba zobuchwepheshe, i-duplexer miniaturization iyadingeka kakhulu.

Okwesibili, i-duplexer kumele kube lula ukuyifaka, ikakhulukazi uma ufaka ama-duplexer namarediyo. Kufanele iqine, ithembeke, ihlangane, ikwazi ukumelana nomthelela othile nokudlidliza, ikakhulukazi ucingo olungenantambo lwendawo ethile. Siyazi ukuthi i-duplexer yamanje isetshenziswa kakhulu amapharamitha ukuze kutholwe izidingo zemvamisa yokusebenza kwayo. Uma ukwakheka kwe-duplexer kungaguquki, kungenzeka ukuthi kubangele ukuthi ucingo olungenantambo lwehlise isithunzi, ngisho nesamukeli esivuthayo. Okubalulekile kancane. Ngaphezu kwalokho, iwusizo kakhulu njengesiteshi sokufuduka esinokhahlo, esidinga ukuthi i-duplexer iqinisekise ikhwalithi yokuxhumana ngaphakathi kwebanga lokushisa elihambisanayo. Ngokuvamile, i-duplex kufanele ibe nebanga lokushisa elicacile lokusebenza futhi ibe nezinkomba zokuzinza kokushintsha kwezinga lokushisa ukuze ihlangabezane nezidingo zokusetshenziswa kwawo wonke umshini.

 

 

Isingeniso

I-duplex evamile iqukethe izihlungi eziyisithupha ezimelana nemigqa, i-resonant ngayinye idluliswa futhi yamukelwe imvamisa. Isihlungi sokugcina esisamukelayo sivusa imvamisa yokudlulisa futhi sivimbele isamukeli sentambo yamandla okudlulisa, futhi isihlungi sokugcina esidlulisayo sizwakalisa imvamisa yokwamukela. Amanye ama-duplex awafakiwe amalebula futhi atholwe kuphela Okuphansi kanye nokuPhakeme kuphela, njenge-doublock Low = 450, ephezulu = 460, okubonisa ukuthi isiphetho se-LOW singajoyina i-terminal engu-450 mega receiver HIGH ukuze ujoyine isidlulisi samamegabhayithi angu-460, noma ingabe Isiphetho ESIPHANSI sizoxhunywa kusidlulisi samamegabhayithi angu-450. Itheminali engu-HIGH ixhunywe kusamukeli esingu-460 megabyte, futhi imvamisa yokudlulisela nokwamukela ingahlehliswa, kodwa i-transmit frequency 460 ayikwazi ukuxhunywa ku-duplexer 450 megabytes ukugwema ukulimala esiteshini kanye ne-duplexer.

 

 

Khetha

I-duplexer kufanele yenziwe ngendlela oyifisayo ngokuya ngefrikhwensi yokudlulisa umsakazo. 400 megabye frequency umehluko 10 MHz duplexer umsebenzi umkhawulokudonsa kungaqinisekisa ukuthi ukuhlukaniswa cishe 90 dB, futhi iphoyinti elilodwa lefrikhwensi inokusebenza okukodwa kokukodwa okungu-120 dB. Uma imvamisa yokusetshenziswa idlula ububanzi obuluhlaza be-duplexer, ukuhlukaniswa kokudlulisela nokwamukela kuzokhuphuka kakhulu, futhi isifunda esamukelayo asisebenzi kahle ngenxa yokuzwela kwengxenye edlulisiwe. Itheminali ye-radiographing ye-amateur U isigaba ngokuvamile sithola ama-megabytes angu-5 Hz, i-duplexer esetshenzisiwe i-narrowband design, eqinisekisa ukuthi ukuhlukaniswa akwehliswa, kodwa umkhawulokudonsa osebenzayo uyancipha, futhi ungu-100 kHz. Ukuzijwayeza kufakazele ukuthi ukusetshenziswa kwama-duplexer kungcono kunokusebenzisa izinti ezimbili.

 

Singakwazi futhi ukwenza ngokwezifiso izingxenye ze-rf passive ngokuya ngezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
