Kingtone Bi-Directional Amplifiers system yakagadzirirwa kugadzirisa matambudziko eiyo isina simba nharembozha, iyo yakachipa zvakanyanya pane kuwedzera Base Station nyowani (BTS).Kushanda kukuru kweRF Bi-Directional Amplifiers system ndeyekugamuchira yakaderera-simba chiratidzo kubva kuBTS kuburikidza neredhiyo frequency kutapurirana uye wobva waendesa chiratidzo chakasimudzirwa kunzvimbo dzisina kuvharwa netiweki.Uye iyo nharembozha inokwidziridzwa uye kuendeswa kuBTS kuburikidza neyakapesana.
◇ High linearity PA;High system kuwana;
◇ Intelligent ALC tekinoroji;
◇ Intelligent AGC tekinoroji;
◇ Yakazara duplex uye yakakwirira kuzviparadzanisa kubva kumusoro kumusoro kuenda kudownlink;
◇ otomatiki Operation nyore kushanda;
◇ Maitiro akabatanidzwa ane kuita kwakavimbika;
◇ Yemunharaunda uye kure yekutarisa (isarudzo) ine otomatiki kukanganisa alarm & kure kure;
◇ Dhizaini yemamiriro ekunze ekuisa-mamiriro ekunze ese;
