Inkqubo ye-Kingtone Bi-Directional Amplifiers yenzelwe ukucombulula iingxaki zesiginali yeselula ebuthathaka, enexabiso eliphantsi kunokongeza iSikhululo esitsha seSiseko (BTS).Ukusebenza okungundoqo kwe-RF Bi-Directional Amplifiers inkqubo kukufumana umqondiso wamandla aphantsi osuka kwi-BTS ngosasazo lwamaza kanomathotholo emva koko usasaze umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isiginali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.
◇ Ulandelelwano oluphezulu PA;Ukuzuza kwenkqubo ephezulu;
◇ Ubuchwephesha be-ALC obukrelekrele;
◇ Ubuchwephesha be-AGC obukrelekrele;
◇ I-duplex epheleleyo kunye nokwahlukaniswa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink;
◇ Ukusebenza okuzenzekelayo ukusebenza kakuhle;
◇ Ubuchule obudityanisiweyo kunye nokusebenza okuthembekileyo;
◇ Ujongo lwasekhaya kunye nolukude (ukhetho) nge-alam yempazamo ezenzekelayo & nolawulo olukude;
◇ uyilo lokumelana nemozulu kufakelo lwemozulu yonke;
