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.

External Configurable Output Filter Bandwidth

The LMV221 has an RF power detection range from

−45 dBm to −5 dBm and is ideally suited for direct

use in combination with a 30-dB directional coupler.

Additional low-pass filtering of the output signal can

be achieved by means of an external resistor and

capacitor. shows a detector with an additional output

low pass filter. The filter frequency is set with R_Sand

trans-impedance gain (R_TRANS). The filter frequency is

IEEE 802.11b, g (WLAN)

set with C_P//C_TRANSand R_P//R_TRANS

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.
