Block Downconverters (LNBs)

Mumasystem ekutaurirana, kuitira kuti zvikwanisike kutapurirana masaini uye kuwana mukana wekushandisazve nzira, kuwanda kwemasaini anotumirwa kwakakwira kwazvo, saka kushandurwa kwemasaini kakawanda chinhu chakakosha pakutsvagisa masisitimu ekutaurirana. Zvichienderana nemamiriro ezvinhu kushandurwa kwemasaini kusati kwatanga uye mushure mekushandurwa kwemasaini, kunogona kukamurwa kuita kushandurwa kwepasi (kuderedza masaini) uye kushandurwa kwepamusoro (kuwedzera masaini).
Mumugamuchiri, kana chiratidzo chepakati chefrequency chinowanikwa mushure mekusanganiswa chiri pasi pechiratidzo chekutanga, saka nzira iyi yekusanganisa inonzi block downconverters (LNBs).
Nzira ye block downconverters ndeyekuwanza chiratidzo chinogamuchirwa nechiratidzo che local oscillator chinogadzirwa ne local oscillator, uye wobva wawana chiratidzo chakashandurwa kuburikidza ne low-pass filter. Zviratidzo zviviri zvakawedzerwa zvinogona kukamurwa kuita kusanganisa chaiko uye kusanganisa kwakaoma kuburikidza nekumiririra chaiko kana kwakaoma.
Chinangwa che block downconverters ndechekuderedza frequency ye carrier yesignal kana kubvisa zvakananga frequency ye carrier kuti uwane baseband signal. Nekuda kwe circuit yayo iri nyore uye mutengo wayo wakaderera, nzira ye down conversion inoshandiswa zvakanyanya mumidziyo yehurumende nemidziyo yemauto ine zvinodiwa zvishoma zvekushanda.

Kushandiswa:

1. Satellite TV: LNBs zvinhu zvakakosha mumasisitimu ekugamuchira TV yesatellite. Dzinoiswa panzvimbo yepakati peantenna yesatellite (paraboloid kana dish), dzinogamuchira chiratidzo cheTV chinotumirwa nesatellite, uye dzinochishandura kuita chiratidzo chepakati chinogona kugadziriswa neanogamuchira.
2. Indaneti yeSatellite: Mumasystem eInternet yeSatellite, ma amplifiers anoshandiswa kugamuchira data reInternet rinotumirwa kubva kumasatellite. Mudziyo wemushandisi unogamuchira data kuburikidza neLNB uye unorigadzirisa nekushandisa kuburikidza nemodem.
3. Kutaurirana neSatellite: MaRF amplifiers anoshandiswa zvakanyanya muhurongwa hwakasiyana-siyana hwekutaurirana nesatelite, kusanganisira mafoni esatellite, nhepfenyuro dzesatelite, kutumira data resatelite, nezvimwewo. Anobatsira kugamuchira nekugadzirisa mhando dzakasiyana dzemasaini ekutaurirana anotumirwa kubva kumasatelite.
4. Kucherechedza Nyika uye Kuona Zviri Kure: Mune mamwe mashandisirwo ekutarisa Nyika uye kuona zviri kure, ma microwave amplifiers anoshandiswa kugamuchira data rekuona zviri kure rinotumirwa kubva kuma satellite. Data iri rinogona kushandiswa mukutarisa mamiriro ekunze, kutarisa zvakatipoteredza, yambiro yenjodzi nedzimwe nzvimbo.
Muchidimbu, maLNB anoita basa rakakosha muhurongwa hwemazuva ano hwekutaurirana nesatellite uye anoshandiswa zvakanyanya mukuparadzira terevhizheni, kuwana internet, kutaurirana nedata uye mumabasa akasiyana-siyana ehunyanzvi.

QualwaveInopa mhando dzakasiyana dzeBlock Downconverters (LNBs) muS~Ka-Band, ine tembiricha yeruzha ye45~240K. Migumo ine mhando dzakasiyana dzekuzadzisa zvinodiwa nevatengi.
