Li-amplifiers tsa Boleng bo Phahameng tsa Chaena tse Customized 136-174MHz VHF Band Selective Bi-directional Amplifiers (BDA)
1. High ho itšehla thajana feletseng duplex moralo, bonolo ho kenya.
2. Palo e tlase ea lerata, e phahameng e amohela kutloisiso.
3. Ka mosebetsi oa ALC le MLC ho netefatsa matla a tsitsitseng a tlhahiso.
4. Tšebeliso e tlaase ea matla, tšireletso ea tikoloho le ho boloka matla.
5. Moralo oa sebopeho sa modular, habonolo ho ntlafatsa sistimi.
6. High Q cavity filter le SAW surface acoustic wave filter, e phahameng ka ntle ho sehlopha sa ho hana.
7. Amohela sebuela-hōle se tsoetseng pele ka ho fetesisa lefatšeng, se holisa matla sa LDMOS sa intermodulation e tlase.
8. Amohela theknoloji e tsoetseng pele ea digital PLL, TCXO, OCXO, botsitso ba maqhubu le ho nepahala ho phahameng.
9. Ts'ebetso e phethahetseng ea ho lekola marang-rang e hole le ea lehae.
10. Mosebetsi oa moralo o sa keneleng metsi bakeng sa maemo ohle a leholimo ka tlung le kantle.

Bi-Directional Amplifier BDA ke eng?
Bi-Directional Amplifier (kapa BDA) e sebelisoa bakeng sa ntlafatso ea khaso ea seea-le-moea sa Setsi sa RF meahong, lithaneleng kapa libakeng tse nang le moriti.BDA's e na le likarolo tse 'maloa: Antenna ea mofani e bokella lets'oao ho tsoa marulelong moo e leng matla ebe e le isa ho BDA bakeng sa ho holisa.Letšoao le atolositsoeng le fetisetsoa ho antenna e le 'ngoe kapa ho feta libakeng tse nang le tšireletso e fokolang.Li-BDA li fumaneha ka lihlopha tse ngata tse ikhethileng: VHF, UHF, 700MHz, 800MHz, le cellular/LTE joalo-joalo.
Libaka tse ngata li na le matšoao a itseng, eseng libakeng tsohle tse hlokahalang setšeng.Ka mohlala, hotele e ka 'na ea e-ba le letšoao mekatong e ka holimo, empa eseng sebakeng sa boikhathollo.Ho fana ka lets'oao ka har'a parkkade, re ne re kenya lenakana ho nka lets'oao ho tsoa sebakeng sa sele kapa se pheta-pheta libakeng tsa ts'ebetso, re le fe seamplifier ebe re le isa ho li-antenna tse ling tse haufi le libaka tse nang le khaello ea tšireletso.kgaso.
