The The MikroElektronika's RF Meter 3 Click is a compact add on board that collects information, analyses RF power, and displays information in an easy to read digital format. This board features the LT5581, a low power monolithic precision RMS power detector from Analog Devices. The RMS detector uses a proprietary technique to accurately measure the RF power in a range from 2GHz up to 2.6GHz, 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. This Click board is suitable for precision power measurement and control for various RF standards including GSM or EDGE, CDMA, CDMA2000, W-CDMA, TD-SCDMA, UMTS, LTE, and WiMAX.
