LT5570 Datasheet

40mhz To 2.7ghz Mean-squared Power Detector

Manufacturer: Linear Technology (now Analog Devices)

LT5570 Overview

The LT®5570 is a 40MHz to 2.7GHz monolithic Logarithmic Mean-Squared RF power detector. It is capable of RMS measurement of an AC signal with wide dynamic range, from 52dBm to 13dBm depending on frequency. The power of the AC signal in an equivalent decibel-scaled value is precisely converted into DC voltage on a linear scale, independent of the crest factor of the waveforms.
