LMH2110 8-GHz Logarithmic RMS Power Detector with 45-dB Dynamic Range  
1 Features  
3 Description  
The LMH2110 is a 45-dB Logarithmic RMS power  
detector particularly suited for accurate power  
measurement of modulated RF signals that exhibit  
large peak-to-average ratios; that is, large variations  
of the signal envelope. Such signals are encountered  
in W-CDMA and LTE cell phones. The RMS

a
The device has an RF frequency range from 50 MHz  
to 8 GHz. It provides an accurate, temperature and  
supply insensitive output voltage that relates linearly  
to the RF input power in dBm. The LMH2110 device  
has excellent conformance to a logarithmic response,  
enabling easy integration by using slope and intercept  
only, reducing calibration effort significantly. The  
device operates with a single supply from 2.7 V to  
5 V. The LMH2110 has an RF power detection range  
from –40 dBm to 5 dBm and is ideally suited for use

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
