Emebere eriri ugboro 380-385 MHz (uplink) / 390-395 MHz (downlink) iji dozie nsogbu nke mgbaàmà ekwentị na-adịghị ike, nke dị ọnụ ala karịa ịgbakwunye ọdụ ọdụ ọhụrụ (BTS).Isi ọrụ nke sistemu Amplifiers RF Bi-Directional bụ ịnata mgbama dị ala sitere na BTS site na mgbasa ozi ugboro redio wee bufee mgbaama na mpaghara ebe mkpuchi netwọk ezughị oke.A na-ebuwanyekwa akara ekwentị mkpanaaka ma bufee ya na BTS site na nke ọzọ.
Isi ihe ngwaahịa:
● Na modularized imewe, mfe maka mmezi
● Software remote nlekota oru (Oghere Usoro ọdụ ụgbọ mmiri), mfe makammezi na njikwa.
● IP55 uzuzu uzuzu & mgbochi mmiri, na-achọrọ ala dị ala na gburugburu nrụnye;
● Na elu-linearity ike amplifier na elu-ajụ duplexer, ike ịjụ intermodulation na spurious mgbama.
