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 Duplexer

Na'urar duplexer ita ce babbar kayan haɗin wurin aiki biyu na ƙasashen waje da kuma tashar relay, wadda ke raba siginar watsawa da karɓa, don tabbatar da cewa karɓa da aikawa na iya aiki yadda ya kamata. Ya ƙunshi saitin matatun bandpass guda biyu na mitoci daban-daban, yana guje wa siginar watsawa ta gida zuwa ga mai karɓa.

Tsarin duplex ɗin da aka saba amfani da shi ya ƙunshi matattara shida masu jure zare, kowanne sautin ana watsa shi kuma ana karɓar mitar. Matatar ƙarshen karɓa tana yin sauti da mitar watsawa kuma tana hana mai karɓar wutar lantarki, kuma matatar ƙarshen watsawa tana yin sauti da mitar karɓa. Wasu duplexers ba a yiwa lakabi da su ba kuma ana karɓar su ne kawai Ƙananan da HIGH, kamar doublock Low = 450, high = 460, wanda ke nuna cewa ƙarshen LOW zai iya haɗa tashar mai karɓar HIGH mai mega 450 don haɗawa da mai watsa HIGH mai megabyte 460, ko kuma za a haɗa ƙarshen LOW da mai watsa 450 megabyte. An haɗa tashar HIGH da mai karɓar 460 megabyte, kuma ana iya juyawa mitar watsawa da karɓa, amma ba za a iya haɗa mitar watsa 460 da mai karɓar 450 megabyte don guje wa lalacewa ga tashar da mai karɓar 450 ba.

Ya kamata a keɓance na'urar duplexer bisa ga mitar watsa rediyo. Bambancin mita 400 na megabye, bandwidth na aikin duplexer 10 MHz zai iya tabbatar da cewa warewar ta kai kimanin 90 dB, kuma wurin mita ɗaya yana da warewar aiki guda ɗaya na 120 dB. Lokacin da mitar amfani ta wuce faɗin raw na duplexer, warewar watsawa da karɓar za su ƙaru sosai, kuma da'irar karɓa ba ta aiki yadda ya kamata saboda yanayin sashin da aka watsa. Sashen tashar rediyo mai son U gabaɗaya yana karɓar megabytes 5 Hz, na'urar duplexer da aka yi amfani da ita ƙira ce ta narrowband, wanda ke tabbatar da cewa warewar ba ta ragu ba, amma bandwidth ɗin aiki ya ƙanƙanta, kuma 100 kHz ne. Aiki ya tabbatar da cewa amfani da na'urorin duplexer ya fi amfani da eriya biyu.
