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.

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.

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, RFIN1 is  
active. In case BS = LOW, RFIN2 is active.  
WCDMA  
CDMA2000  
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.
