It can be used for electronic fence micro-hot spot distribution control system, mainly deployed in urban hot spots, without affecting the normal communication between the mobile phone and the base station, to collect information such as the IMEI number and IMSI number of the mobile phone, achieve the most accurate data acquisition, data analysis, tracking alarm and other functions, and improve the efficiency of public security personnel handling cases and the response ability of handling emergency incidents. Typical deployment scenarios include: airport, railway station and other entrances, bars, KTV, Internet cafes and other entertainment places, banks, hotels, government offices, residential areas and other gates and entrances.
Main functions and performance parameters:

Core advantage:
The amplifier unit adopts asymmetric Doherty structure, and on the basis of ensuring large peak power, the current efficiency of the whole module is still up to 25%, which is nearly 10% higher than that of the Class AB amplifier. By optimizing its AM/AM and AM/PM curves, the current efficiency is guaranteed. The nonlinear distortion index is also taken into account.
Application scenario:
Electronic fence system, cellular communication system.
