LMV232 Dual-Channel Integrated Mean Square Power Detector for CDMA & WCDMA

Check for Samples: LMV232

FEATURES

DESCRIPTION

The LMV232 dual RF detector is designed for RF

transmit power measurement in mobile phones. This

dual mean square IC is especially suited for accurate

power measurement of RF signals exhibiting high

peak-to-average ratios used in 3G and UMTS/CDMA

applications. The LMV232 saves calibration steps

and system certification and is highly accurate. The

circuit operates with a single supply from 2.5 to 3.3V.

•

>20 dB Square-Law Detection Range

2 Sequentially Selectable RF Inputs

Low Power Consumption Shutdown Mode

Externally Configurable Gain and LF Filter

Bandwidth.

•

Internal 50Ω RF Termination Impedance

Optimized for Use with 20 dB Directional

Coupler

The LMV232 contains a mean square detector with

two sequentially selectable RF inputs. The RF input

power range of the device has been optimized for use

with a 20 dB directional coupler, without the need for

additional external components. A single external RC

combination between FB and OUT provides an

externally configurable gain and LF filter bandwidth of

the device.

APPLICATIONS

•

3G Mobile Communications

UMTS

The device has two digital interfaces. A shutdown

function is available to set the device in a low-power

shutdown mode. In case SD = HIGH, the device is in

shutdown, if SD = LOW the device is active. The

Band-Select function controls the selection of the

active RF input channel. In case BS = HIGH, RF_IN1 is

active. In case BS = LOW, RF_IN2 is active.

WCDMA

TD-SCDMA

RF Control

Wireless LAN

PC Card and GPS Modules

The dual mean square detector is offered in an 8-

bump DSBGA 1.5 x 1.5 x 0.6 mm package. This

DSBGA package has the smallest footprint and

height.
