LMV232

Dual-Channel Integrated Mean Square Power Detector

for CDMA & WCDMA

General Description

Features

20 dB square-law detection range

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 measure-

ment 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.

n 2 sequentially selectable RF inputs

n Low power consumption shutdown mode

n Externally configurable gain and LF filter bandwidth.

n Internal 50Ω RF termination impedance

n Optimized for use with 20 dB directional coupler

n Lead free 8-bump micro SMD package 1.5 x 1.5 x 0.6

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

n 3G mobile communications

n UMTS

n WCDMA

n CDMA2000

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 se-

lection of the active RF input channel. In case BS = HIGH,

RF_IN1 is active. In case BS = LOW, RF_IN2 is active.

n TD-SCDMA

n RF control

n Wireless LAN

n PC Card and GPS modules

The dual mean square detector is offered in an 8-bump

micro SMD 1.5 x 1.5 x 0.6 mm package. This micro SMD

package has the smallest footprint and height.
