AD8318 RF Logarithmic Detector Module, 1MHz-8GHz 70dB RSSI RF Power Meter Signal Measurement Board for SDR Wireless Testing

Product Usage:

This radio frequency detector is designed using the AD8318 chip from ADI Company. It is equipped with a power supply and voltage stabilization circuit, ensuring that the detection accuracy approaches the official data. The working frequency range is 1 - 8000 MHz. It can detect radio frequency signals ranging from -65 to -5 dBm and outputs the detected signal strength in the form of a direct current voltage (in dBm, logarithmic mode). This converts the radio frequency signal into a direct current voltage output. The amplitude or power of the radio frequency signal corresponds to the output voltage. It can be used for signal strength indication (RSSI), spectrum analyzer, gain control, etc.
