Dual band signal repeater for GSM 900Mhz and DCS 1800MHz

Dual band signal repeater for GSM 900Mhz and DCS 1800MHz A High-gain linear power amplifier B ALC technology .

Dual band signal repeater for GSM 900Mhz and DCS 1800MHz

Cell phone signal amplifier is designed to solve the blind signal designed for mobile phone products. As the mobile phone signal is transmitted by electromagnetic waves to establish a communications link, the building of the barrier, in some tall buildings inside the basement of some places such as malls, restaurants, places of entertainment such as karaoke OK sauna and massage, underground civil air defense projects, subway stations and many other places, cell phone signals can not reach and can not use the phone. Cell phone signal amplifier can solve these problems in a particular place as long as the installation of a mobile phone signal amplifier system, the entire range of mobile phone signals can be well used, to which staff or customers great convenience .
