China High Quality Makonda 136-174MHz VHF Band Selective Bi-directional Amplifiers (BDA)
1. High kudzipatula zonse duplex kapangidwe, zosavuta kukhazikitsa.
2. Chiwerengero chochepa chaphokoso, cholandira kwambiri.
3. Ndi ALC ndi MLC ntchito kuonetsetsa khola linanena bungwe mphamvu.
4. Kugwiritsa ntchito mphamvu zochepa, kuteteza chilengedwe ndi kupulumutsa mphamvu.
5. Modular kapangidwe kamangidwe, mosavuta kukweza dongosolo.
6. High Q patsekeke fyuluta ndi SAW pamwamba acoustic wave fyuluta, mkulu kunja kukana gulu.
7. Khalani ndi mzere wapamwamba kwambiri padziko lonse lapansi, zokulitsa mphamvu za LDMOS zokhala ndi intermodulation.
8. Landirani ukadaulo wapamwamba wa digito PLL, TCXO, OCXO, kukhazikika pafupipafupi komanso kulondola kwambiri.
9. Wangwiro kutali ndi m'deralo kuwunika maukonde ntchito.
10. Ntchito yopangira madzi kwa nyengo yonse yamkati ndi kunja.
Kapangidwe ka Makabati Awiri a BDA pazosankha za kasitomala
Kodi Bi-Directional Amplifier BDA ndi chiyani?
Bi-Directional Amplifier (kapena BDA) imagwiritsidwa ntchito popititsa patsogolo kufalikira kwa mawayilesi Patsamba pa ma siginecha a RF mnyumba, machubu kapena madera omwe ali ndi mithunzi.BDA's ili ndi zigawo zingapo: Mlongoti wopereka ndalama umasonkhanitsa chizindikiro kuchokera padenga pomwe chili cholimba ndikuchipereka ku BDA kuti chikulitse.Chizindikiro chokulirapo chimaperekedwa ku tinyanga imodzi kapena zingapo zogawa m'malo omwe sakhala bwino.Ma BDA akupezeka m'magulu ambiri apadera: VHF, UHF, 700MHz, 800MHz, ndi ma cellular/LTE etc.
Malo ambiri amakhala ndi chizindikiro, osati m'malo onse ofunikira patsamba.Mwachitsanzo, hotelo ikhoza kukhala ndi chizindikiro pazipinda zapamwamba, koma osati pa parkkade.Kuti tipereke chizindikiro mu parkkade, timayika mlongoti kuti tinyamule chizindikiro kuchokera pamalo a selo kapena chobwereza kuchokera kumalo ogwirira ntchito, kudyetsa ku amplifier kenaka kupita ku tinyanga zambiri zomwe zili pafupi ndi madera omwe alibe chidziwitso.kufalitsa.
