Bindpo RF Logarithmic Detector, 1M-10000MHz AD8317 Radio Frequency Logarithmic Detector Power Meter, for RF Signal Power Detection/Radio Frequency Signal Detection

The product is designed by using AD8317 chip, and is used for RF signal power detection..
Can detect power in -55dBm to -0dBm of an RF signal, so that the RF signal is converted to 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, thus expanding the dynamic range of the detected signal, which ranges reach 55dB..
It can be widely used in radio frequency signal detection, signal power measurement, environmental field strength detection..
It can also be used as part of automatic gain control and automatic level control..
