LMH2110

SNWS022D –JANUARY 2010–REVISED JUNE 2015

LMH2110 8-GHz Logarithmic RMS Power Detector with 45-dB Dynamic Range

1 Features

3 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. The RMS

•

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

•

measurement topology inherently ensures

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. The LMH2110 device

has excellent conformance to a logarithmic response,

enabling easy integration by using slope and intercept

only, reducing calibration effort significantly. The

device operates with a single supply from 2.7 V to

5 V. The LMH2110 has an RF power detection range

from –40 dBm to 5 dBm and is ideally suited for use

The device is active for EN = High; otherwise, it is in

a low power-consumption shutdown mode. To save

power and prevent discharge of an external filter
