LMH2100 50-MHz to 4-GHz 40-dB Logarithmic Power Detector for CDMA and WCDMA  
1 Features  
3 Description  
The LMH2100 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  
4 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.

Multi-Band Operation from 50 MHz to 4 GHz  
0.5-dB Accurate Temperature Compensation  
External Configurable Output Filter Bandwidth  
0.4-mm Pitch DSBGA Package  
The LMH2100 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. Typical Application: Output RC Low Pass  
Filter shows a detector with an additional output low  
pass filter. The filter frequency is set with RS and CS.  
2 Applications  
UMTS/CDMA/WCDMA RF Power Control  
GSM/GPRS RF Power Control  
PA Modules  
Typical Application: Feedback (R)C Low Pass Filter  
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  
IEEE 802.11b, g (WLAN)  
is 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.
