LMH2110 - 8 GHz 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, i.e.

large variations of the signal envelope.

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

Key Features

  • 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 Wide supply range from 2.7V to 5V Tiny 6-bump microSMD package.

DataSheet.in LMH2110 PRODUCT BRIEF LMH2110 PRODUCT BRIEF January 7, 2010 8 GHz Logarithmic RMS Power Detector with 45 dB Dynamic Range 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, i.e. large variations of the signal envelope. Such signals are encountered in W-CDMA and LTE cell phones. The RMS measurement topology inherently ensures a modulation insensitive measurement. The device has an RF frequency range from 50 MHz to 8 GHz. It provides an accurate, temperature and supply insensitive, output voltage that relates linearly to the RF input power in dBm.
