AD8310/AD8313/AD8317/AD8318 Logarithmic Detector Module RF Signal Log Output Power Meter 1-440MHz/1-8000MHz/1M-10GHz/0.1-2.5GHz

Logarithmic Detector RF Signal Log Output Power Meter Controller Feature: 1. This power meter is designed with for ADI's chip and used for RF signal power detection. 2. Detection frequency range is 1-440MHz, 1-8000MHz, 1M-10GHz, 0.1-2.5GHz, which can detect an RF signal with a power of -55dBm to -0dBm, and convert this RF signal into DC voltage output. 3. The greater the RF signal amplitude or power, the higher the output voltage, and the output voltage is proportional to the logarithm of the input signal amplitude, which expands the dynamic range of the detected signal by 55dB.
