LTC5582
40MHz to 10GHz
RMS Power Detector with
57dB Dynamic Range
FEATURES DESCRIPTION Frequency Range: 40MHz to 10GHz
n Linear Dynamic Range: Up to 57dB
n Accurate RMS Power Measurement of High Crest
Factor Modulated Waveforms
n Exceptional Accuracy Over Temperature: ±0.5dB (Typ)
n Low Linearity Error within Dynamic Range
n Single-Ended or Differential RF Inputs
n Fast Response Time: 90ns Rise Time
n Low Supply Current: 41.6mA at 3.3V (Typ)
n Small 3mm × 3mm DFN10
n AEC-Q100 Qualified for Automotive Applications The LTC®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. The DC output is buffered with a …
