I-FMUSER FUTV3627 Indoor (5W) MMDS 2.5G 2.7G Broadband TV Broadcast DVB-s DVB-t Transmitter Amplifier

I-FMUSER FUTV3627 2.5G 2.7G i-broadband TV esakaza i-MMDS yedijithali (isistimu yokusabalalisa ama-microwave eziteshi eziningi) I-5W DVB-s DVB-t yasendlini isidluliseli singasekela ukuthunyelwa kwe-broadband yesiteshi esisodwa noma amashaneli amaningi. Ukudluliswa kwesiteshi esisodwa ngokuvamile kudinga isihlanganisi samandla e-microwave ukuze sihlanganise ama-microwave esiteshi esisodwa, bese siwathumela othini nge-waveguide. Ngale ndlela, amandla e-microwave angathuthukiswa futhi afinyelele amabanga amade. Umsebenzi wokudlulisa i-broadband yeziteshi eziningi awudingi isihlanganisi samandla kodwa uxhuma umthombo we-IF kusidlulisi ngokusebenzisa isihlanganisi. Ngemuva kokuguqulwa kwefrikhwensi, ukuhlunga, nokukhulisa, ithumela isignali ku-antenna nge-waveguide. Ngale ndlela, amandla e-microwave aphansi futhi nebanga lokudlulisela lifushane. Isidluliseli se-MMDS singahlinzeka ngeshaneli yesignali enomkhawulokudonsa omkhulu wama-200MHz. Umsindo wesigaba esiphansi se-oscillator yendawo uvumela i-FUTV3627 ukuthi isetshenziswe ekudluliseni isignali ye-analog nedijithali. Ukusetshenziswa kobuchwepheshe obuthuthukisiwe bokukhulisa umugqa ophezulu kungakhuphula amandla okudlulisela ngenkathi kunciphisa ukuhlanekezela okungewona umugqa kanye nokusetshenziswa kwamandla okuphelele. Ngokufanayo, umsebenzi we-AGC ungagcina ukuphuma kwamandla njalo, futhi isizungeza singanikeza ukuvikelwa kwe-VSWR. Zonke lezi zici zenza i-FUTV3627 isetshenziswe kabanzi ezinhlelweni zokusakaza.

Izinzuzo

Umsindo wesigaba se-oscillator sendawo esiphansi, esitholakala kukho kokubili ukudluliselwa kwe-analog nedijithali.

Ukusetshenziswa kwamandla okuphansi kanye nomklamo we-superlinear ukuthuthukisa amandla okudlulisela, nokunciphisa ukuhlanekezela okungaqondile.

Sekela umsebenzi we-AGC ngokuphuma kwamandla okuqhubekayo ukuze uvumele isidlulisi ukuqina nokuthembeka okuhle.

Ukulawula okugcwele kwephaneli yangaphambili yedijithali, ukusebenza okulula.

Iwindi le-LCD elibonisa amandla okukhiphayo, isimo se-digital attenuator, isimo sokusebenza se-AGC/MGC, kanye ne-voltage.

Kulula ukufaka, ukubukeka okuhle.

Alukho ulwazi.
