Functions of cell phone signal amplifier/repeater :

1. High-gain linear power amplifier;
2.Automatic level control;
3.Ultra-low noise receiver amplifier;
4.No interference to the base station and no need to adjust the parameters of the original system and base stations after installation.
5. Stable and reliable EMC design
6. It neither increases base station background noise nor declines the communication quality of base station

7. Full-duplex communication mode;
8. Spurious emission, beautiful outlook and smart siz
