LMV225/LMV226/LMV228 RF Power Detector for CDMA and WCDMA
General 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 sing...
