LMV227 Production RF Tested, RF Power Detector for CDMA and WCDMA
General Description
The LMV227 is a 30 dB RF power detector 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 5V.
The LMV227 has 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 capa...
