Fasahar Microwave ta Sichuan Keenlion——Mai haɗawa

Fasahar Microwave ta Sichuan Keenlion An kafa ta a shekarar 2004, Sichuan Keenlion Mircrowve techenology CO., Ltd. ita ce babbar masana'antar kayan aikin Passive Mircrowve a Sichuan Chengdu, China.

Muna ba da kayan aikin madubi masu aiki da yawa da kuma ayyuka masu alaƙa don amfani da microwave a gida da waje. Kayayyakin suna da araha, gami da masu raba wutar lantarki daban-daban, masu haɗa hanya, matattara, masu haɗawa, masu haɗa duplexers, kayan haɗin da aka keɓance na musamman, masu rabawa da masu zagayawa. An tsara samfuranmu musamman don yanayi daban-daban da yanayin zafi mai tsauri. Ana iya tsara ƙayyadaddun bayanai bisa ga buƙatun abokin ciniki kuma suna aiki ga duk madaidaitan madaukai masu shahara tare da bandwidth daban-daban daga DC zuwa 50GHz.

Mai haɗawa

A cikin tsarin sadarwa ta wayar hannu mara waya, babban aikin mai haɗawa shine haɗa siginar shigarwa da yawa da kuma fitar da su zuwa tsarin rarrabawa na cikin gida iri ɗaya

A aikace-aikacen injiniya, ana buƙatar fitarwar cibiyar sadarwa ta 800MHz C, cibiyar sadarwa ta 900MHz G ko wasu mitoci daban-daban a lokaci guda. Ta amfani da mai haɗawa, saitin tsarin rarrabawa na cikin gida na iya aiki a cikin tashar mitar CDMA, tashar mitar GSM ko wasu tashoshin mita a lokaci guda.

Ana amfani da mahaɗin gabaɗaya a ƙarshen watsawa. Aikinsa shine haɗa siginar RF guda biyu ko fiye da aka aika daga masu watsawa daban-daban zuwa ɗaya sannan a aika su zuwa na'urorin RF da eriya ke watsawa, yayin da ake guje wa hulɗar da ke tsakanin siginar kowace tashar jiragen ruwa.

Masu haɗaka gabaɗaya suna da tashoshin shigarwa guda biyu ko fiye da haka kuma tashar fitarwa guda ɗaya ce kawai. Keɓewar tashoshin jiragen ruwa muhimmin ma'auni ne don bayyana ikon sigina biyu ba sa shafar juna. Gabaɗaya ana buƙatar ya zama fiye da 20dB.

Mai haɗa gadar 3dB yana da tashoshin shigarwa guda biyu da tashoshin fitarwa guda biyu, kamar yadda aka nuna a Hoto na 2. Ana amfani da shi sosai don haɗa mitoci biyu na masu ɗaukar kaya marasa waya da kuma ciyar da su cikin eriya ko tsarin rarrabawa. Idan aka yi amfani da tashar fitarwa guda ɗaya kawai, ɗayan tashar fitarwa yana buƙatar a haɗa shi da nauyin 50W. A wannan lokacin, akwai asarar 3dB bayan an haɗa siginar. Wani lokaci ana buƙatar amfani da tashoshin fitarwa guda biyu, don haka babu kaya kuma babu asarar 3dB.

Haɗa karɓa da aika wayar hannu ta sigina zuwa eriya ɗaya. A cikin tsarin GSM, saboda transceiver ɗin ba ya cikin lokaci ɗaya, wayar hannu za ta iya cire duplexer ɗin don ware transceiver ɗin, kuma ta yi amfani da mai haɗa transceiver mai sauƙi kawai don haɗa siginar aikawa da karɓa zuwa eriya ɗaya ba tare da tsangwama ga juna ba.

Ga da'irar karɓa, eriya tana karɓar siginar, tana shiga tashar karɓa ta hanyar mahaɗin, tana gauraya da siginar oscillator ta gida da aka karɓa (watau siginar VCO da aka karɓa da mai haɗa mita ya samar), tana canza siginar mita mai yawa zuwa siginar mita mai matsakaici, sannan quadrature yana rage siginar don samar da siginar I da Q da aka karɓa; Sannan ana gudanar da GMSK (Gaussian filter minimum frequency shift keying) dedulation don canza siginar analog zuwa siginar dijital, sannan a aika zuwa sashin sarrafa baseband.

Ga da'irar watsawa, ɓangaren baseband yana aika kwararar bayanai na firam ɗin TDMA (tare da ƙimar 270.833kbit / s) don daidaitawar GSMK don samar da siginar watsawa ta I da Q, wanda daga nan ake aika shi zuwa mai canza watsawa don daidaitawa zuwa band na mitar watsawa. Bayan ƙara ƙarfin lantarki, mai watsawa yana aika shi ta eriya.

Mai haɗa mita yana samar da siginar oscillator ta gida da ake buƙata don sauya mita ga na'urar watsawa da karɓa, kuma yana amfani da fasahar madauki mai kulle lokaci don daidaita mitar. Yana samun ma'aunin mita daga da'irar ma'aunin agogo.
