Designed using AD8317 chip and RF signal strength used for detection. It can detect the power between -55dBm and 0dBm of an RF signal, thus converting the RF signal into DC voltage output. The larger the amplitude or power of the RF signal, the higher the output voltage, and the output voltage is directly proportional to the logarithm of the input signal amplitude, thus expanding the dynamic range of the detected signal, these ranges reach 55dB.
Can be widely used in radio frequency signal detection, signal strength measurement, environmental field strength detection. It can also be used as part of automatic gain control and automatic level control.
Applications
