Description

This is 40MHz to 10GHz RMS Power Detector. LTC5582 40MH- to 10GH- RMS Power Detector with 57dB Dynamic Range Features Frequency Range: 40MH- to 10GH- 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 Description The LTC®5582 is a 40MH- to 10GH- 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, incl.
