LMH2110

PRODUCT BRIEF

8 GHz Logarithmic RMS Power Detector with 45 dB

Dynamic Range

General Description

Features

The LMH2110 is a 45 dB Logarithmic RMS power detector

particularly suited for accurate power measurement of mod-

ulated 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 in-

sensitive measurement.

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

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's excellent conformance to a logarithmic

response enables an easy integration by using slope and in-

tercept only, reducing calibration effort significantly. The de-

vice operates with a single supply from 2.7V to 5V. The

LMH2110 has an RF power detection range from -40 dBm to

5 dBm and is ideally suited for use in combination with a di-

rectional coupler. Alternatively a resistive divider can be used

as well.

Minimal Slope and Intercept variation

Shutdown functionality

Wide supply range from 2.7V to 5V

■

Tiny 6-bump microSMD package

Applications

Multi Mode, Multi band RF power control

■

GSM/EDGE

CDMA/CDMA2000

W-CDMA

—

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

power consumption shutdown mode. To save power and pre-

vent discharge of an external filter capacitance, the output

(OUT) is high-impedance during shutdown.

OFDMA

LTE

Infrastructure RF Power Control

■

The LMH2110 power detector is offered in a tiny 6-bump mi-

croSMD package.
