30 dB Linear in dB Power Detection Range  
Output Voltage Range 0.2 to 2V  
Logic Low Shutdown  
detectors intended for use in CDMA and WCDMA  
applications. The device has an RF frequency range  
from 450 MHz to 2 GHz. It provides an accurate  
temperature and supply compensated output voltage  
that relates linearly to the RF input power in dBm.  
The circuit operates with a single supply from 2.7V to  
5.5V. The LMV225/LMV226/LMV228 have an  
integrated filter for low-ripple average power detection  
of CDMA signals with 30 dB dynamic range.  
Additional filtering can be applied using a single  
external capacitor.

in  
combination  
with  
resistive  
taps.  
The  
LMV226/LMV228 have a detection range from –15  
dBm to 15 dBm and are intended for use in  
combination with a directional coupler. The LMV226  
is equipped with a buffered output which makes it  
suitable for GSM, EDGE, GPRS and TDMA  
applications.

PA Modules  
The device is active for Enable = HI, otherwise it is in  
a low power consumption shutdown mode. During  
shutdown the output will be LOW. The output voltage  
ranges from 0.2V to 2V and can be scaled down to  
meet ADC input range requirements.  
The LMV225/LMV226/LMV228 power detectors are  
offered in the thin 1.0 mm x 1.0 mm x 0.6 mm  
DSBGA package and the ultra thin 1.0 mm x 1.0 mm  
x 0.35 mm DSBGA package. The LMV225 and the  
LMV228 are also offered in the 2.2 mm x 2.5 mm x  
0.8 mm WSON package.
