Mikroe RF Meter 3 Click collects information, analyzes RF power, and displays information in an easy-to-read digital format. The board features the Analog Devices LT5581 low-power monolithic precision RMS power detector. The RMS detector uses a proprietary technique to accurately measure the RF power in a range from 2GHz up to 2.6GHz. It’s well-suited for signals with high crest factors. It outputs a DC voltage in linear scale proportional to an RF input signal power in dBm.
