Description
General part information
LMH2100 Series
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 to4 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.
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. shows a detector with an additional output low pass filter. The filter frequency is set with RSand CS.
shows a detector with an additional feedback low pass filter. Resistor RPis optional and will lower the Trans impedance gain (RTRANS). The filter frequency is set with CP//CTRANSand RP//RTRANS.
