LMV221 50-MHz to 3.5-GHz 40-dB Logarithmic Power Detector for CDMA and WCDMA  
1 Features  
3 Description  
The LMV221 is a 40-dB RF power detector intended  
for use in CDMA and WCDMA applications. The  
device has an RF frequency range from 50 MHz to  
3.5 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 2.7 V to 3.3 V.

External Configurable Output Filter Bandwidth  
The LMV221 has an RF power detection range from  
45 dBm to 5 dBm and is ideally suited for direct  
use in combination with a 30-dB directional coupler.  
Additional low-pass filtering of the output signal can  
be achieved by means of an external resistor and  
capacitor. shows a detector with an additional output  
low pass filter. The filter frequency is set with RS and  
CS.

shows a detector with an additional feedback low  
pass filter. Resistor RP is optional and lowers the  
trans-impedance gain (RTRANS). The filter frequency is  
IEEE 802.11b, g (WLAN)  
set with CP//CTRANS and RP//RTRANS  
.
The device is active for Enable = High, otherwise it is  
in a low power consumption shutdown mode. To save  
power and prevent discharge of an external filter  
capacitance, the output (OUT) is high-impedance  
during shutdown.
