LMV232 Dual-Channel Integrated Mean Square Power Detector for CDMA & WCDMA February 2005 LMV232 Dual-Channel Integrated Mean Square Power Detector for CDMA & WCDMA General Description The LMV232 dual RF detector is designed for RF transmit power measurement in mobile phones. This dual mean square IC is especially suited for accurate power measurement of RF signals exhibiting high peak-to-average ratios used in 3G and UMTS/CDMA applications. The LMV232 saves calibration steps and system certification and is highly accurate. The circuit operates with a single supply from 2.5 to 3.3V. The LMV232 contains a mean square detector with two sequentially selectable RF inputs.
