www.ti.com SNWS013L – AUGUST 2003 – REVISED MARCH 2013 LMV225/LMV226/LMV228 RF Power Detector for CDMA and WCDMA
Check for Samples: LMV225, LMV226, LMV228 FEATURES 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 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. 1 2 30 dB Linear in dB Power Detection Range
