2. Precautions:

1) It is forbidden to transmit for a long time under no-load or serious mismatch of load impedance.

2) Do not increase the working voltage. Although it can increase the power, the power consumption of the product will increase,

Reliability goes bad.

3) Pay attention to anti-static measures. There is a common grounding point between the devices. Connect the RF interface before power up.
