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.
