Ikhwalithi Ephakeme Yase-China Eyenziwe Ngezifiso 136-174MHz VHF Band Selective Bi-directional Amplifiers (BDA)
1. Idizayini eyi-duplex egcwele ukuzihlukanisa ephezulu, kulula ukuyifaka.
2. Isibalo somsindo ophansi, ukuzwela okuphezulu.
3. Ngomsebenzi we-ALC kanye ne-MLC ukuze kuqinisekiswe amandla okukhiphayo azinzile.
4. Ukusetshenziswa kwamandla okuphansi, ukuvikelwa kwemvelo nokonga amandla.
5. Isakhiwo se-Modular design, kalula ukuthuthukisa uhlelo.
6. Isihlungi esiphezulu se-Q kanye nesihlungi se-SAW surface acoustic wave, siphezulu ngenxa yokwenqatshwa kwebhendi.
7. Yamukela ukulandelana okuphezulu okuthuthuke kakhulu emhlabeni, isikhulisi samandla se-LDMOS esine-intermodulation ephansi.
8. Yamukela ubuchwepheshe obuthuthukisiwe bedijithali be-PLL, i-TCXO, i-OCXO, ukuzinza kwamafrikhwensi kanye nokunemba okuphezulu.
9. Umsebenzi ophelele wokuqapha inethiwekhi yendawo nendawo.
10. Umsebenzi wokuklama ongangeni manzi waso sonke isimo sezulu esingaphakathi nangaphandle.
Idizayini Yamakhabhinethi Amabili ye-BDA yenketho yeklayenti
Yini i-Bi-Directional Amplifier BDA?
I-Bi-Directional Amplifier (noma i-BDA) isetshenziselwa ukuthuthukisa ukusakazwa komsakazo Kusayithi lamasignali e-RF ezakhiweni, emigudu noma ezindaweni ezinomthunzi.I-BDA inezingxenye ezimbalwa: I-antenna yokunikela iqoqa isignali kusuka ophahleni lwendlu lapho inamandla khona bese iyiletha ku-BDA ukuze ikhulise.Isignali ekhulisiwe ilethwa othingo owodwa noma ngaphezulu wokusabalalisa ezindaweni ezingahlangani kahle.Ama-BDA atholakala kumabhendi amaningi athile: VHF, UHF, 700MHz, 800MHz, kanye neselula/LTE njll.
Izindawo eziningi zinesignali ethile, hhayi kuzo zonke izindawo ezidingekayo esizeni.Isibonelo, ihhotela lingase libe nesignali ezitezi ezingaphezulu, kodwa hhayi endaweni yokupaka.Ukuze sinikeze isignali ku-parkkade, sizofaka uthi ukuze sithathe isiginali esizeni seseli noma isiphindaphindi ezindaweni zokusebenza, siyiphakele kusikhulisi bese siyikhiphela kuma-antenna amaningi atholakala eduze nezindawo ezingambozwe kahle.ukusabalala.
