Small 3mm × 3mm 10-Lead DFN Package 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. The
LT5570 is suitable for precision RF power measurement and …
