TI LMV221SD/NOPB

50MHz ~ 3.5GHz手机，CDMA，CDMA2000，EDGE，GSM，GPRS，TDMA，W-CDMA-45dBm ~ 5dBm

Overview

The LMV221SD/NOPB 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.

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.
