n Small 3mm Г— 3mm DFN10 The LTCВ®5582 is a 40MHz to 10GHz RMS responding power
detector. It is capable of accurate power measurement
of an AC signal with wide dynamic range, from –60dBm
to 2dBm 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 input signal waveforms. The LTC5582
is suitable for precision RF power measurement and level
control for a wide variety of RF standards, including LTE,
WiMAX, W-CDMA, CDMA2000, TD-SCDMA, and EDGE. …
