The LMV225/LMV226/LMV228 are 30 dB RF power detectors intended for use in CDMA and WCDMA applications
The LMV225, LMV226, and LMV228 are 30 dB RF power detectors intended for use in CDMA and WCDMA applications. The device provides an accurate temperature and supply compensated output voltage that relates linearly to the RF input power in dBm. It operates with a single supply from 2.7V to 5.5V and features an integrated filter for low-ripple average power detection.
