This power meter is designed with for 's AD8317 chip and used for RF signal power detection._x000D_ Detection frequency range is 1M-10GHz, which can detect an RF signal with a power of -55dBm to -0dBm, and convert this RF signal into output._x000D_ The greater the RF signal amplitude or power, the higher the output voltage, and the output voltage is proportional to the of the input signal amplitude, which expands the dynamic range of the detected signal by 55dB._x000D_ Widely applied to RF signal detection, signal power measurement, environmental field strength detection, and can also be used as an integral part of automatic gain control and automatic level control._x000D_ This logarithmic detector can withstand high and low temperatures, stable and durable. Item Type: Logarithmic Detector_x000D_ SPI interface is easy to connect with and single chip microcomputer with 2.54mm pitch pins_x000D_ Temperature Measurement Range: 0 to 1024_x000D_ Converter Temperature Resolution: 0.25_x000D_ Working Voltage: DC 3. 0~5. 5V_x000D_ Working Current: 50mA_x000D_ Operating Temperature Range: -20~85_x000D_ Colour: green_x000D_ Material: plastic Package Contents:_x000D_ 1 * RF Log Detector Only the above package content, other products are not included._x000D_ Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
