About this item

  • WIDE APPLICATION---The logarithmic power detector could be widely used radio frequency detection, power measurement, environmental field strength detection, or as a part of automatic gain control and automatic level control
  • 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
  • 55dBm to 0dBm---The logarithmic power detector can detect power in -55dBm to 0dBm of an RF , so that the RF is converted to DC voltage output
  • 55dB---The greater the amplitude or power of the RF , the higher the output voltage, and the output voltage is directly proportional to the logarithm of the input amplitude, thus expanding the dynamic range of the detected , which ranges reach 55dB
  • AD8317 CHIP---The logarithmic power detector is designed by using AD8317 chip, and is used for RF power detection

Comes without any description. Nothing tells you what value translates into what db?!?Once you search the internet for hours for helpful instructions you will figure out that this thing does pretty much nothing except waste your time. What a joke!Goes straight back. Total waste of time and money!

The schematic shows what it should look like when you're finished and not what is on the board. I've attached an image that explains how to set it to measurement mode and also how to adjust the slope swing. If you prefer to use something that doesn't look like it was made by a monkey, you can use the AD8317 datasheet on the Analog Devices website.Other than that, item works as intended. Will purchase again.

Consistant reading with changes in power but scale changes alot with increase in frequency. Don't know if I can find a use for this unless the signal frequency is constant.
