LMV221  
50 MHz to 3.5 GHz 40 dB Logarithmic Power Detector for  
CDMA and WCDMA  
General Description  
Features  
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 ac-  
curate 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 3.3V.  
40 dB linear in dB power detection range  
Output voltage range 0.3 to 2V  
Shutdown  
Multi-band operation from 50 MHz to 3.5 GHz  
0.5 dB accurate temperature compensation  
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 realized by means of an external  
resistor and capacitor. Figure (a) shows a detector with an  
additional output low pass filter. The filter frequency is set with  
RS and CS.  
2.2 mm x 2.5 mm x 0.8 mm LLP 6 package  
Applications  
UMTS/CDMA/WCDMA RF power control  
GSM/GPRS RF power control  
Figure (b) shows a detector with an additional feedback low  
pass filter. Resistor RP is optional and will lower the Trans  
impedance gain (RTRANS). The filter frequency is set with  
PA modules  
IEEE 802.11b, g (WLAN)  
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 pre-  
vent discharge of an external filter capacitance, the output  
(OUT) is high-impedance during shutdown.  
The LMV221 power detector is offered in the small 2.2 mm x  
2.5 mm x 0.8 mm LLP package.  
Typical Application  
(a) LMV221 with output RC Low Pass Filter  
(b) LMV221 with feedback (R)C Low Pass Filter
