Amakuru

Ikoranabuhanga rya Sichuan Keenlion Microwave Yashinzwe mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ni iya mbere mu gukora ibice bya Passive Mircrowave i Sichuan Chengdu, mu Bushinwa.

Dutanga imikorere-yimikorere ya mirrowave hamwe na serivisi zijyanye na porogaramu ya microwave murugo no mumahanga. Ibicuruzwa birahenze cyane, harimo gutandukanya imbaraga zitandukanye, guhuza icyerekezo, gushungura, guhuza, duplexers, ibikoresho byabigenewe byabigenewe, kwigunga no kuzenguruka. Ibicuruzwa byacu byateguwe byumwihariko kubidukikije bikabije nubushyuhe. Ibisobanuro birashobora gutegurwa ukurikije ibyo umukiriya asabwa kandi birakurikizwa kumurongo wose usanzwe kandi uzwi cyane hamwe numuyoboro utandukanye kuva DC kugeza 50GHz.

Duplexer

Duplexer nigikoresho nyamukuru cyibikorwa byamahanga bibiri byakazi hamwe na sitasiyo ya relay, aribyo gutandukanya ibimenyetso byohereza no kwakira, byemeza ko ibyakiriwe no kohereza bishobora gukora neza. Igizwe nibice bibiri bya bande ya filteri yumurongo utandukanye, wirinda kohereza ibimenyetso byaho kubakira.

Uwitekaduplexerni Byakoreshejwe mu kwimura itumanaho no gukorera mu gasozi nk umunara utagenzuwe, ubwayo igena imikoreshereze yimiterere n’imikorere.

Ubwa mbere, turizera ko duplexer ari nto, yoroshye. Kugeza ubu, bitewe nubunini bwa duplexer nibindi bibazo bya tekiniki, duplexer ya radiyo yintoki ntabwo yigeze itangazwa. Ariko kumwanya ushobora gutangwa mumashanyarazi, imodoka, nibindi, kandi hariho nogukoresha terefone idafite insinga hamwe nibibazo byo gukwirakwiza ubushyuhe, kugirango kugirango huzuzwe ibindi bipimo bya tekiniki, miniaturizasi ya duplexer irakenewe cyane.

Icya kabiri, duplexer igomba kuba yoroshye kuyishyiraho, cyane cyane mugihe ushyiraho duplexer na radiyo. Igomba kuba ikomeye, yizewe, yoroheje, igomba kuba ishobora guhangana ningaruka zimwe na zimwe zinyeganyega, cyane cyane terefone idafite umugozi kubidukikije. Turabizi ko duplexer iriho ubu ikwirakwizwa cyane kugirango tumenye ibisabwa inshuro zayo. Niba imiterere ya duplexer idahinduka, birashoboka gutera terefone idafite umugozi kwangirika, ndetse niyakira. Birahambaye cyane. Ikigeretse kuri ibyo, ni ingirakamaro cyane nka sitasiyo yimuka ikaze cyane, bisaba duplexer kugirango ireme ryitumanaho muburyo bukwiranye nubushyuhe bukora. Muri rusange, duplex igomba kuba ifite ubushyuhe bugaragara kandi ikagira ibipimo byerekana ihindagurika ryubushyuhe kugirango byuzuze ibisabwa imashini yose.

 

 

Intangiriro

Ubusanzwe duplex igizwe na esheshatu zidashobora kwihanganira muyunguruzi, buri resonant yanduzwa kandi yakiriwe inshuro. Kwakira amaherezo ya filteri yumvikanisha inshuro zoherejwe kandi ikabuza kohereza imiyoboro yumurongo wakira, kandi ihererekanyabubasha ryungurura ryumvikana inshuro yakira. Duplexers zimwe ntizanditseho kandi zakiriwe gusa Hasi na HIGH gusa, nko gukuba kabiri = 450, hejuru = 460, byerekana ko iherezo rya LOW rishobora kwinjiza mega 450 yakira HIGH terminal kugirango ryinjire muri megabayiti 460, cyangwa se iherezo rya LOW rihuzwa na megabayiti 450. HIGH terminal ihujwe na megabayiti ya 460, kandi ihererekanyabubasha n’iyakirwa rishobora guhinduka, ariko itumanaho rya 460 ntirishobora guhuzwa na duplexer 450 megabayite kugirango birinde kwangirika kuri sitasiyo na duplexer.

 

 

Hitamo

Duplexer igomba guhindurwa ukurikije radiyo yohereza. 400 megabye itandukanyirizo rya 10 MHz duplexer yumurongo mugari irashobora kwemeza ko kwigunga bigera kuri 90 dB, naho umwanya umwe wumurongo ufite imikorere imwe ya 120 dB. Iyo inshuro zikoreshwa zirenze ubugari bwa duplexer mbisi, ihererekanyabubasha no kwakirwa byiyongera cyane, kandi imiyoboro yakira ntabwo ikora neza kubera sensibilité y igice cyanduye. Amateur ya radiografiya ya U igice muri rusange yakira megabaýt 5 Hz, duplexer ikoreshwa ni igishushanyo mbonera, cyemeza ko kwigunga bitagabanuka, ariko umurongo wogukora uragabanuka, kandi ni 100 kHz. Imyitozo yerekanye ko gukoresha duplexer ari byiza kuruta gukoresha antene ebyiri.

 

Turashobora kandi gutegekanya ibice bya rf bikurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
