Main function:
The main function of this product is to use the wireless power transmission equipment of low power amplifier, the small device with large power to make communication distance more clearer sound like strangers.
Product features:
The amplifier is equipped with a half duplex automatic transceiver circuit. It is suitable for all U segment interphone and data transmission equipment in the market. It can support digital DMR, DPMR, P25, C4FM, SFK frequency hopping and traditional linear analog mode perfectly.
Use note:
In use, the amplifier must be mounted with an antenna corresponding to the frequency, otherwise it will burn the equipment because of standing wave too high.
Application range:
The product is widely used in self drive intercom, small power relay amplification, 433 digital transmission, HAM radio, unmanned aerial vehicle 433, 1-5W handheld walkie talkie, power amplification

50W
hand power amplifier, power amplifier and intercom ordinary moments
after cars in Taiwan, this product with automatic transceiver circuit,
suitable for all U interphone on the market, can be the perfect support
for DMR, DPMR, P25 digital and traditional linear simulation model.
Working principle:
Emission: 1-5W power input to the amplifier, output 20-80W (different versions of power difference), the launch of the power amplifier panel (TX red LED light) light, the launch state can not receive all the income of the signal.
Receive: when TX red LED lamp goes out, the amplifier is in the receiving signal state.
When the internal temperature of the amplifier reaches 40 degrees Celsius, the cooling fan automatically works. After the temperature drops to normal temperature, the fan automatically stops working.

Experiments
have shown that if you use the antenna on the car in the middle of the
car roof, it is best to have a 0.02 gain, and in other places, the gain
is negative
Package:
- 1x 30W AMP
- 1x power cable
