LMH2110 - Logarithmic RMS Power Detector

General Description

The LMH2110 is a 45-dB Logarithmic RMS power detector particularly suited for accurate power measurement of modulated RF signals that exhibit large peak-to-average ratios; that is, large variations of the signal envelope.

Such signals are encountered in W-CDMA and LTE cell phones.

Key Features

  • 1 Wide Supply Range from 2.7 V to 5 V.
  • Logarithmic Root Mean Square Response.
  • 45-dB Linear-in-dB Power Detection Range.
  • Multi-Band Operation from 50 MHz to 8 GHz.
  • LOG Conformance Better than ±0.5 dB.
  • Highly Temperature Insensitive, ±0.25 dB.
  • Modulation Independent Response, 0.08 dB.
  • Minimal Slope and Intercept Variation.
  • Shutdown Functionality.
  • Tiny 6-Bump DSBGA Package 2.
