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.

Manuniyar fasaha
1. Matakin haɗin kai: bambanci kai tsaye tsakanin ƙarfin fitarwa daga tashar haɗin kai da ƙarfin siginar shigarwa lokacin da ƙarfin siginar ya ratsa ta mahaɗin.
2. Matsayin Keɓewa: yana nufin keɓancewa tsakanin tashar fitarwa da tashar haɗawa; Gabaɗaya, wannan ma'aunin ana amfani da shi ne kawai don auna ma'aunin microstrip. Kuma yana bambanta bisa ga matakin haɗawa: misali, 5-10db shine 18 ~ 23dB, 15dB shine 20 ~ 25dB, kuma 20dB (gami da sama) shine 25 ~ 30dB; matakin keɓancewa na ma'aunin rami yana da kyau sosai, don haka babu buƙatar wannan ma'aunin.
3. Kai tsaye: yana nufin ƙimar warewar da ke tsakanin tashar fitarwa da tashar haɗawa ba tare da la'akari da ƙimar matakin haɗawa ba. Tunda kai tsaye na microstrip yana raguwa a hankali tare da ƙaruwar matakin haɗawa, babu wani kai tsaye sama da 30dB, don haka babu irin wannan buƙatar ma'aunin ma'auni don mahaɗin microstrip. Kai tsaye na mahaɗin rami gabaɗaya shine 17 ~ 19dB a 1700 ~ 2200MHz, 824 ~ 960MHz: 18 ~ 22dB.
4. Hanyar lissafi: kai tsaye = warewa - haɗawa.
5. Asarar shigarwa: yana nufin ƙimar da aka samu ta hanyar cire ƙimar asarar rarrabawa daga ƙarancin ƙarfin sigina daga ƙarfin sigina ta hanyar mahaɗin zuwa fitarwa. Gabaɗaya, asarar shigarwar mahaɗin microstrip ya bambanta dangane da matakin haɗin gwiwa. Gabaɗaya, shine 0.35 ~ 0.5dB don ƙasa da 10dB da 0.2 ~ 0.5dB don fiye da 10dB.
6. Matsakaicin tsayin raƙuman shigarwa / fitarwa: yana nufin daidaita tashoshin shigarwa / fitarwa, kuma buƙatun kowace tashar gabaɗaya 1.2 ~ 1.4 ne;
7. Juriyar Ƙarfi: yana nufin matsakaicin juriyar aiki wanda zai iya wucewa ta wannan mahaɗin na dogon lokaci (ba tare da lalacewa ba). Gabaɗaya, matsakaicin ƙarfin mahaɗin microstrip shine 30 ~ 70W, kuma na rami shine 100 ~ 200W.
8. Kewayon mita: gabaɗaya, mitar da aka ƙayyade ita ce 800 ~ 2200MHz. A zahiri, mitar da ake buƙata ita ce 824-960MHz da 1710 ~ 2200MHz. Ba a samun mitar matsakaiciyar ba.
9. A cikin band Flatness: yana nufin bambanci tsakanin matsakaicin da mafi ƙarancin matakin haɗin gwiwa a cikin dukkan band ɗin mita da ake da shi. Microstrip gabaɗaya 0.5 ~ 0.2db ne. Kogo: tunda matakin haɗin gwiwa lanƙwasa ne, babu irin wannan buƙata.

Haka kuma za mu iya keɓance abubuwan haɗin rf marasa aiki bisa ga buƙatunku. Kuna iya shigar da shafin keɓancewa don samar da takamaiman bayanai da kuke buƙata.
