Features:
1. The voltage of the amplifier cannot exceed 5V, otherwise it is easy to damage the module.
2. The antenna must be added before the amplifier is powered on, otherwise the power amplifier chip will be easily damaged.
3. The input power of the amplifier should not be greater than ± 3dbm, otherwise it will cause the amplifier to oversaturate and the receiver cannot receive data.
4. The amplifier is in the continuous transmitting state. The power amplifier chip needs to consume 800mA of current. The selected power supply needs to provide a current greater than 1A and install a heat sink to work stably.
5. When the amplifier is working, the transmitting end and the receiving end (when both antennas are installed) should be far away (keep more than one meter) to prevent the signal received by the receiving end from being too large and causing oversaturation, causing the receiving end to fail to receive data or damage.
