LMV225/LMV226/LMV228  
RF Power Detector for CDMA and WCDMA  
General Description  
Features  
n 30 dB linear in dB power detection range  
n Output voltage range 0.2 to 2V  
n Logic low shutdown  
The LMV225/LMV226/LMV228 are 30 dB RF power detec-  
tors 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 com-  
pensated 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 inte-  
grated 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.  
n Multi-band operation from 450 MHz to 2000 MHz  
n Accurate temperature compensation  
n Packages:  
— micro SMD thin 1.0 mm x 1.0 mm x 0.6 mm  
— micro SMD ultra thin 1.0 mm x 1.0 mm x 0.35 mm  
— LLP 2.2 mm x 2.5 mm x 0.8 mm  
(LMV225 and LMV228)  
The LMV225 has an RF power detection range from –30  
dBm to 0 dBm and is ideally suited for direct use in combi-  
nation with resistive taps. The LMV226/LMV228 have a de-  
tection 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.  
Applications  
n CDMA RF power control  
n WCDMA RF power control  
n CDMA2000 RF power control  
n 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 re-  
quirements.  
The LMV225/LMV226/LMV228 power detectors are offered  
in the thin 1.0 mm x 1.0 mm x 0.6 mm micro SMD package  
and the ultra thin 1.0 mm x 1.0 mm x 0.35 mm micro SMD  
package. The LMV225 and the LMV228 are also offered in  
the 2.2 mm x 2.5 mm x 0.8 mm LLP package.
