Katswiri wa UHF 10W Bi-Directional Amplifier
Dongosolo la Kingtone Bi-Directional Amplifiers lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kuwonjezera Base Station (BTS).Kugwira ntchito kwakukulu kwa RF Bi-Directional Amplifiers system ndikulandila siginecha yamphamvu yotsika kuchokera ku BTS kudzera pawayilesi yawayilesi kenako ndikutumiza siginecha yokwezeka kumadera omwe kulumikizidwa kwa netiweki sikukwanira.Ndipo siginecha yam'manja imakulitsidwanso ndikutumizidwa ku BTS kudzera mbali ina.

Main Features
High linearity PA;Kupindula kwakukulu kwadongosolo;
ukadaulo wanzeru wa ALC;
Duplex kwathunthu komanso kudzipatula kwapamwamba kuchokera ku uplink kupita ku downlink;
Makinawa Ogwiritsa ntchito yabwino;
Integrated njira ndi ntchito odalirika;
Bandwidth imatha kukhazikitsidwa kuchokera ku 0.2-25MHz mu gulu lantchito.
Kuyang'anira kwanuko komanso patali (posankha) ndi ma alarm angozi okha & chiwongolero chakutali;
Mapangidwe a Weatherproof pakuyika kwanyengo zonse;

Mapulogalamu Aukadaulo a UHF 10W Bi-Directional Amplifier
Kukulitsa kufalikira kwa ma siginecha amtundu wakhungu wodzaza pomwe chizindikiro ndi chofooka
kapena osapezeka.
Panja: Mabwalo a ndege, Madera Oyendera alendo, Maphunziro a Gofu, Tunnel, Mafakitole, Maboma a Migodi, Midzi ndi zina.
M'nyumba: Mahotela, Malo Owonetserako, Zipinda Zapansi, Zogula
Malo ogulitsira, Maofesi, Malo Olongedza, etc.
Zimagwiritsidwa ntchito makamaka pazochitika zotere:
Wobwereza amatha kupeza malo oyikapo omwe angalandire chizindikiro choyera cha BTS pamlingo wokwanira mokwanira popeza Rx Level pamalo obwereza iyenera kukhala yoposa -70dBm
Ndipo amatha kukwaniritsa kufunikira kwa kudzipatula kwa mlongoti kuti apewe kudzidzidzimutsa.
