Product Overview

The LMV221SD/NOPB is a 50MHz to 3.5GHz 40dB Logarithmic Power Detector for CDMA and WCDMA. 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 to 3.3V. The LMV221 has an RF power detection range from -45 to -5dBm and is ideally suited for direct use in combination with a 30dB 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 RS and CS. 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 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.
