TI LMH2100TM/NOPB

50MHz ~ 4GHz手机，W-CDMA，CDMA，GSM，UMTS-45dBm ~ -5dBm

Overview

The LMH2100TM/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 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 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.
