YWBL-WH Logarithmic Power Detector Meter AD8317 1M-10GHz 60dB RF Power Meter Logarithmic Detector Controller for Amplifier 50 Ohms

  • AD8317 CHIP---The logarithmic power detector is designed by using AD8317 chip, and is used for RF signal power detection.
  • -55dBm to 0dBm---The logarithmic power detector can detect power in -55dBm to 0dBm of an RF signal, so that the RF signal is converted to DC voltage output.
  • 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.
  • WIDE APPLICATION---The logarithmic power detector could be widely used radio frequency signal detection, signal power measurement, environmental field strength detection, or as a part of automatic gain control and automatic level control.
