SNWS018D – DECEMBER 2006 – REVISED JUNE 2016 LMV221 50-MHz to 3.5-GHz 40-dB Logarithmic Power Detector for CDMA and WCDMA
1 Features 3 Description The LMV221 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
3.5 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. 1 2.7-V to 3.3-V Supply Voltage
