Function: The product is designed using AD8317 chip and is used to detect RF signal power. Can detect the power of an RF signal in -55dBm to 0dBm, so that the RF signal is converted into a DC voltage output.
The greater 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, extending the dynamic range of the detected signal, whose ranges reach 55 dB. It can be widely used in capturing high-frequency signals, measuring signal performance and detecting ambient field strength. It can also be used as part of automatic gain control and automatic level control. Application: PA setpoint control and level monitoring of the RF transmitter; power monitoring in a wireless line transmitter; RSSI measurements in base stations, WLAN, WiMAX and radar
