LMV228 - (LMV225 - LMV228) RF Power Detector

Download the LMV228 datasheet PDF. This datasheet also covers the LMV225 variant, as both devices belong to the same (lmv225 - lmv228) rf power detector family and are provided as variant models within a single manufacturer datasheet.

Description

The LMV225/LMV226/LMV228 are 30 dB RF power detectors intended for use in CDMA and WCDMA applications.

The device has an RF frequency range from 450 MHz to 2 GHz.

It provides an accurate temperature and supply compensated output voltage that relates linearly to the RF input power in dBm.

The device has an RF frequency range from 450 MHz to 2 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 2.7V to 5.5V. The LMV225/LMV226/LMV228 have an integrated filter for low-ripple average power detection of CDMA signals with 30 dB dynamic range. Additional filtering can be applied using a single external capacitor.
