China High Quality Yakagadzirirwa 136-174MHz VHF Band Selective Bi-directional Amplifiers (BDA)
1. High isolation full duplex design, nyore kuisa.
2. Yakaderera ruzha chimiro, yakakwirira kugamuchira senitivity.
3. NeALC uye MLC basa rekuona simba rakagadzikana rinobuda.
4. Kuderera kwesimba rekushandisa, kuchengetedza kwezvakatipoteredza uye kuchengetedza simba.
5. Modular chimiro dhizaini, nyore kusimudzira sisitimu.
6. High Q cavity filter uye SAW surface acoustic wave filter, yakakwirira kunze kwekuramba kwebhendi.
7. Gamuchira mutsara wepamusoro-soro wepasi rose, wakaderera intermodulation LDMOS simba amplifier.
8. Gamuchira iyo yepamusoro yedhijitari PLL, TCXO, OCXO tekinoroji, frequency kugadzikana uye yakakwirira kunyatso.
9. Yakakwana kure uye yemunharaunda network monitoring basa.
10. Mvura yekugadzira basa remamiriro ekunze ese mukati nekunze.
Makabati maviri Dhizaini yeBDA yesarudzo yemutengi
Chii chinonzi Bi-Directional Amplifier BDA?
A Bi-Directional Amplifier (kana BDA) inoshandiswa kuOn-Site redhiyo kukwidziridzwa kwemasaini eRF muzvivakwa, tunnels kana nzvimbo dzine mumvuri.BDA's ine zvinhu zvishoma: Anopa antenna inounganidza chiratidzo kubva padenga remba payakasimba uye ichiendesa kuBDA kuti iwedzere.Chiratidzo chakakwidziridzwa chinounzwa kune imwe kana akawanda ekugovera antenna munzvimbo dzisina kuvharika.MaBDA anowanikwa mumabhendi mazhinji chaiwo: VHF, UHF, 700MHz, 800MHz, uye cellular/LTE nezvimwe.
Nzvimbo zhinji dzine chiratidzo, kwete munzvimbo dzese dzinodiwa pasaiti.Semuenzaniso, hotera inogona kunge iine chiratidzo pauriri hwepamusoro, asi kwete mupaki.Kuti tipe chiratidzo mu parkkade, taiisa antenna yekutora chiratidzo kubva kusero saiti kana inodzokorora kubva kunzvimbo dzekushanda, toidyisa kune amplifier tobva taenda kune mamwe antenna ari padhuze nenzvimbo dzisina kufukidzwa.coverage.
