FMUSER FUTV3627 Na Cikin Gida (5W) MMDS 2.5G 2.7G Broadband TV Broadcast DVB-s DVB-t Amplifier Mai watsawa

FMUSER FUTV3627 2.5G 2.7G watsa shirye-shiryen watsa shirye-shiryen TV na dijital MMDS (tsarin rarraba microwave mai yawan tashoshi) 5W DVB-s DVB-t mai watsawa na cikin gida na iya tallafawa watsa tashoshi ɗaya ko tashoshi da yawa. Watsawar tashoshi ɗaya yawanci yana buƙatar mahaɗar wutar lantarki ta microwave don haɗa microwaves mai tashoshi ɗaya, sannan aika su zuwa eriya ta hanyar jagorar wave. Ta wannan hanyar, ana iya haɓaka ƙarfin microwave kuma a kai ga nesa mai nisa. Aikin watsa labarai na tashar tashoshi da yawa baya buƙatar mai haɗa wuta amma yana haɗa tushen IF zuwa mai watsawa ta hanyar mahaɗa. Bayan jujjuya mitar, tacewa, da haɓakawa, yana aika sigina zuwa eriya ta hanyar waveguide. Ta wannan hanyar, ikon microwave yana da ƙasa kuma nisan watsawa gajere ne. Mai watsawa na MMDS zai iya samar da tashar sigina tare da iyakar bandwidth na 200MHz. Ƙarƙashin ƙaramar amo na oscillator na gida yana ba da damar yin amfani da FUTV3627 a watsa siginar analog da dijital. Yin amfani da fasaha na haɓakawa na gabaɗaya na linzamin kwamfuta na iya ƙara ƙarfin watsawa yayin da rage ɓarna marar layi da yawan amfani da wutar lantarki. Hakazalika, aikin AGC na iya kula da wutar lantarki akai-akai, kuma mai rarrabawa zai iya ba da kariya ta VSWR. Duk waɗannan fasalulluka sun sa FUTV3627 ake amfani da su sosai a tsarin watsa shirye-shirye.

Karancin ƙarar oscillator na gida, akwai don watsa analog da dijital.

Ƙarƙashin amfani da wutar lantarki da ƙira mafi girma don inganta ƙarfin watsawa, da rage ɓarnar da ba ta dace ba.

Taimakawa aikin AGC tare da ci gaba da fitowar wutar lantarki don ba da damar mai watsawa mai kyau kwanciyar hankali da aminci.
