I-UHF 10W eyi-Bi-Directional Amplifier yobungcweti
Uhlelo lwe-Kingtone Bi-Directional Amplifiers luklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokwengeza i-Base Station entsha (BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Bi-Directional Amplifiers ukuthola isignali yamandla aphansi evela ku-BTS ngokusakazwa kwamafrikhwensi omsakazo bese idlulisela isignali ekhulisiwe ezindaweni lapho ukutholakala kwenethiwekhi kungenele.Futhi isignali yeselula nayo iyakhuliswa futhi idluliselwe ku-BTS ngendlela ehlukile.

Izici Eziyinhloko
I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
Intelligent ALC ubuchwepheshe;
I-duplex ephelele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;
Ukusebenza okuzenzakalelayo ukusebenza okulula;
Isu elihlanganisiwe nokusebenza okuthembekile;
Umkhawulokudonsa ungalungiselelwa ukusuka ku-0.2-25MHz kubhendi yomsebenzi.
Ukuqapha kwasendaweni nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
- Uhlelo lokusebenza&izimo

Izicelo zobungcweti ze-UHF 10W Bi-Directional Amplifier
Ukwandisa ukumbozwa kwesignali yendawo eyimpumputhe yesignali yokugcwalisa lapho isignali ibuthakathaka
noma engatholakali.
Ngaphandle: Izikhumulo Zezindiza, Izifunda Zezokuvakasha, Izifundo Zegalofu, Imigudu, Amafekthri, Izifunda Zezimayini, Imizana njll.
Ngaphakathi: Amahhotela, Izikhungo Zemibukiso, Amagumbi angaphansi, Ukuthenga
Izitolo ezinkulu, Amahhovisi, Izitolo Zokupakisha njll.
Isebenza kakhulu esimweni esinjalo:
Ophindayo angathola indawo yokufaka engathola isignali emsulwa ye-BTS ezingeni eliqinile ngokwanele njengoba Izinga le-Rx esizeni sokuphinda kufanele libe ngaphezu kuka- -70dBm
Futhi ingahlangabezana nemfuneko yokuhlukaniswa kwe-antenna ukugwema ukuzizulisa.
