SNWS021C –JULY 2010–REVISED FEBRUARY 2013  
LMH2120 6 GHz Linear RMS Power Detector with 40 dB Dynamic Range  
Check for Samples: LMH2120

FEATURES  
DESCRIPTION  
The LMH2120 is a 40 dB Linear RMS power detector  
particularly suited for accurate power measurement of  
modulated RF signals that exhibit large peak-to-  
average ratios, i.e, large variations of the signal  
envelope. Such signals are encountered in W-CDMA  
and LTE cell phones. The RMS measurement  
topology inherently ensures a modulation insensitive  
measurement.

Linear Root Mean Square Response  
40 dB Linear-in-V Power Detection Range  
Multi-Band Operation from 50 MHz to 6 GHz  
Lin Conformance Better than ±0.5 dB  
Highly Temperature Insensitive  
Modulation Independent Response  
Minimal Slope and Intercept Variation  
Shutdown Functionality  
The device has an RF frequency range from 50 MHz  
to 6 GHz. It provides an accurate, temperature and  
supply insensitive, output voltage that relates linearly  
to the RF input power in volt. The LMH2120's  
excellent conformance to a linear response enables  
an easy integration by using slope and intercept only,  
reducing calibration effort significantly. The device  
operates with a single supply from 2.7V to 5V. The  
LMH2120 has an RF power detection range from -35  
dBm to 5 dBm and is ideally suited for use in  
combination with a directional coupler. Alternatively, a  
resistive divider can be used.  
Wide Supply Range from 2.7V to 5V

The device is active for EN = 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.
