working principle The transmitting module KT0622 collects the sound source and converts the analog signal into a digital signal through analog to digital conversion. RF radio frequency radiates digital signals into the air to form electrical waves. In order to obtain a longer transmission distance, the electromagnetic wave signal can be amplified by PA and finally passed through the antenna Launch out.
