This power meter is designed with for 's AD8317 chip and used for signal power detection. Detection frequency range is 1M-10GHz, which can detect an signal with a power of -55dBm to -0dBm, and convert this signal into DC voltage output. The greater the 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. Widely applied to 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. This logarithmic detector can withstand high and low temperatures, stable and . Item Type: Logarithmic Detector SPI interface is easy to connect with and single chip microcomputer with 2.54mm pitch pins Temperature Measurement Range: 0℃ to 1024℃ Converter Temperature Resolution: 0.25℃ Working Voltage: DC 3. 0~5. 5V Working Current: 50mA Operating Temperature Range: -20℃~85℃ Colour: green Material: plastic Package Contents: 1 * Log Detector Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
