This power meter is designed for ADI's AD8317 chip and used for RF signal power detection. Detection frequency range is 1 MHz to 10 GHz, capable of detecting RF signals with power from -55 dBm to 0 dBm, and converting the RF signal into DC voltage output. The higher the RF signal amplitude or power, the higher the output voltage. The output voltage is proportional to the logarithm of the input signal amplitude, providing a dynamic range expansion of 55 dB. Widely used in RF signal detection, signal power measurement, environmental field strength detection, and as a component in automatic gain control and automatic level control systems. This logarithmic detector operates reliably under varying temperatures, offering stable and durable performance. Item Type: Logarithmic Detector SPI interface for easy connection to microcontrollers with 2.54 mm pitch pins Working Voltage: DC 3.0–5.5 V Working Current: 50 mA Operating Temperature Range: -20°C to 85°C Color: Green Material: Plastic Package Contents: 1 x RF Log Detector Note: Light shooting and different displays may cause slight color variations between the item in the picture and the actual product. Measurement may vary by +/- 1–3 cm.
