40 dB Power Detection Range  
Very Low Supply Current of 3.4 mA  
Short Response Time of 165 ns  
Stable Conversion Gain of 3.6 V/VRMS  
Multi-Band Operation from 100 MHz to 3 GHz  
Very Low Conformance Error  
High Temperature Stability of ±0.5 dB  
Shutdown Functionality  
between an RF input signal and DC output signal is  
linear. The typical response time of 165 ns makes the  
device suitable for an accurate power setting in  
handsets during a rise time of RF transmission slots.  
It can be used in all popular communications  
standards: 2G/3G/4G/WAP.  
The LMH2121 has an input range from −28 dBm to  
+12 dBm. Over this input range the device has an  
intrinsic high insensitivity for temperature, supply  
voltage and loading. The bandwidth of the device is  
from 100 MHz to 3 GHz, covering 2G/3G/4G/WiFi  
wireless bands.  
Supply Range from 2.6V to 3.3V  
Package:  
–
4-Bump DSBGA, 0.4mm Pitch  
As a result of the unique internal architecture, the  
device shows an extremely low part-to-part variation  
of the detection curve. This is demonstrated by its low  
intercept and slope variation as well as a very good  
linear conformance. Consequently the required  
characterization and calibration efforts are low.  
APPLICATIONS  
•
Multi Mode, Multi band RF power control

–
GSM/EDGE  
CDMA  
The device is active for EN = High; otherwise it is in a  
low power consumption shutdown mode. To save  
power and allow for two detector outputs in parallel,  
the output (OUT) is high impedance during shutdown.

The LMH2121 is offered in a tiny 4-bump DSBGA  
package: 0.866 mm x 1.07 mm x 0.6 mm.
