Fasahar Microwave ta Sichuan Keenlion——Mai haɗawa

Sichuan Keenlion Fasahar Microwave An kafa shi a cikin 2004, Sichuan Keenlion Mircrowave fasaha CO., Ltd. shine babban mai kera na'urorin fasahar Mircrowave mai wucewa a Sichuan Chengdu, China.

Muna samar da kayan aikin mirrowave mai girma da sabis masu alaƙa don aikace-aikacen microwave a gida da waje. Samfuran suna da tsada, gami da masu rarraba wutar lantarki iri-iri, ma'auratan jagora, masu tacewa, masu haɗawa, duplexers, abubuwan da aka keɓance na keɓancewa, masu keɓewa da masu rarrabawa. An tsara samfuranmu musamman don matsanancin yanayi daban-daban da yanayin zafi. Ana iya ƙirƙira ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai bisa ga buƙatun abokin ciniki kuma ana amfani da su ga duk daidaitattun maƙallan mitar mitoci masu shahara tare da bandwidth iri-iri daga DC zuwa 50GHz.

Mai haɗawa

A cikin tsarin sadarwar wayar hannu mara igiyar waya, babban aikin haɗawa shine haɗa siginar shigar da multiband da fitar da su zuwa tsarin rarraba cikin gida iri ɗaya.

A cikin aikace-aikacen injiniya, cibiyar sadarwar 800MHz C, cibiyar sadarwar 900MHz G ko wasu mitoci daban-daban suna buƙatar fitarwa a lokaci guda. Yin amfani da mahaɗa, saitin tsarin rarraba na cikin gida zai iya aiki a rukunin mitar CDMA, rukunin mitar GSM ko wasu madafan mitar a lokaci guda.

Misali, a cikin tsarin eriyar rediyo, ana haɗa siginar shigarwa da fitarwa na nau'ikan nau'ikan mita daban-daban (kamar 145mhz da 435mhz) ta hanyar mahaɗa, sannan a haɗa su da gidan rediyo tare da feeder, wanda ba kawai yana adana feeder ba, har ma yana guje wa matsalolin canza eriya daban-daban.

A cikin aikace-aikacen injiniya, dole ne a haɗa cibiyar sadarwar 800MHz C da cibiyar sadarwar 900MHz G. Yin amfani da mahaɗa, saitin tsarin rarraba na cikin gida zai iya aiki a band ɗin CDMA da band GSM a lokaci guda. Misali, a cikin tsarin eriyar rediyo, ana haɗa siginar shigarwa da fitarwa na nau'ikan nau'ikan mita daban-daban (kamar 145mhz da 435mhz) ta hanyar mahaɗa, sannan a haɗa su da gidan rediyo tare da feeder, wanda ba kawai yana adana feeder ba, har ma yana guje wa matsala ta canza eriya daban-daban..

 

Bayanin ka'ida

Ana amfani da mai haɗawa gabaɗaya a ƙarshen watsawa. Ayyukansa shine haɗa siginar RF biyu ko fiye da aka aika daga masu watsawa daban-daban zuwa ɗaya kuma aika su zuwa na'urorin RF da eriya ke watsawa, tare da guje wa hulɗar siginar kowane tashar jiragen ruwa.

Haɗuwa gabaɗaya suna da tashoshin shigarwa biyu ko fiye da tashar fitarwa guda ɗaya kawai. Keɓanta tashar tashar jiragen ruwa muhimmin ma'auni ne don bayyana ikon sigina biyu kada su shafi juna. Ana buƙatar gabaɗaya ya zama fiye da 20dB.

3dB gada mai haɗawa yana da tashar shigar da bayanai guda biyu da tashoshin fitarwa guda biyu, kamar yadda aka nuna a hoto na 2. Ana amfani da ita don haɗa mitocin jigilar mara waya guda biyu da ciyar da su cikin eriya ko tsarin rarrabawa. Idan aka yi amfani da tashar fitarwa guda ɗaya kawai, sauran tashar fitarwa tana buƙatar haɗawa 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 siginar wayar hannu zuwa eriya ɗaya. A tsarin GSM, saboda na’urar sadarwa ba ta cikin ramin lokaci guda, wayar hannu za ta iya barin duplexer domin kebe na’urar, sai kawai a yi amfani da na’urar sadarwa mai sauki ta hanyar hada sakonni da karban sakonni zuwa eriya daya ba tare da shiga tsakanin juna ba.

Don da'irar karɓa, eriya tana karɓar siginar, shigar da tashar mai karɓa ta hanyar mai haɗawa, yana haɗuwa tare da siginar oscillator na gida da aka karɓa (watau siginar VCO da aka karɓa ta hanyar haɗin mitar), yana canza siginar mai girma zuwa siginar mitar matsakaici, sannan quadrature yana lalata siginar don samar da siginar I da Q da aka karɓa; Sa'an nan GMSK (Gaussian filter mafi ƙarancin maɓallin kewayawa) ana aiwatar da ƙaddamarwa don canza siginar analog ɗin zuwa siginar dijital, sannan a aika zuwa sashin sarrafawa na baseband.

Don da'irar watsawa, ɓangaren baseband yana aika rafin bayanan firam ɗin TDMA (tare da ƙimar 270.833kbit / s) don ƙirar GSMK don samar da siginar watsa I da Q, sannan ana aika zuwa mai juyawa sama don daidaitawa zuwa rukunin mitar watsawa. Bayan haɓaka wutar lantarki, mai watsawa yana aika shi ta eriya.

Mai haɗa mitar mitar yana samar da siginar oscillator na gida da ake buƙata don jujjuya mitar don naúrar watsawa da karɓa, kuma yana amfani da fasahar madauki mai kulle lokaci don daidaita mitar. Yana samun ma'anar mitar daga da'irar nunin agogo.

Da'irar nunin agogo gabaɗaya shine agogon 13mhz. A gefe ɗaya, yana ba da bayanin agogo don da'irar haɗin mitar da agogon aiki don da'irar dabaru.
