AD8318 1MHz-8GHz 70dB Logarithmic Detector Amplifier SiGe Log Amp Module RSSI

AD8317 CHIP---The logarithmic power detector is designed by using AD8317 chip, and is used for RF signal power detection

APPLICATION AREAS---The logarithmic power detector could be used for RF transmitter PA set point control and level monitoring; Power monitoring in a radio line transmitter; RSSI measurements in base stations, WLAN, WiMAX, and radar

55dB---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
