Cell Phone Signal Booster 700/850/1900/1700MHz 45dB 2G 3G 4G Wireless Repeater for Car Use
This 45dB Mobile Phone Cell Phone Signal Booster is designed to boost multiple users with maximum power. It is best used in the following applications:
1)Wide Input Voltage:
Input DC Voltage Range 5-15V
The system detects self-oscillation, first reduces the link gain, then detects the loop, and finds that the self- oscillation is eliminated, the system returns to normal working state, otherwise, the power is turned off to prevent interference signal.
When no user calls, the device works in standby mode, the uplink power amplifier is switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy saving.
4)AGC (Automatic Gain Control):
When the downlink output signal is too strong or self-oscillated, the uplink and downlink can automatically reduce the gain and reduce the interference signal.
5)Automatic Power Shut-down:
When the self-oscillation happens, and the link attenuation value reaches 20dB, the MCU sends out the instruction and shut-down the PA.
6)MGC (Manual Gain Control):
In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-20dB. You can rotate the Manual Gain Control Knob to the OFF state and turn off the corresponding frequency band.
7)ALC(Automatic Level Control):
Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling quality, data transfer quality, avoid the signal self- oscillation, and also very much reduce the interference to the cell tower, even if your house is very close from the cell tower, you don't need to worry about the interference and the trouble cause
