With the ability to measure instantaneously the continuously-variable crest factor signals found within CDMA, W-CDMA, 8-PSK, QAM and OFDM signals, the AD8362 targets IS95, CDMA2000, 3GPP, GSM Edge, MMDS and other broadband access equipment. Applications include cellular base station transmit power level control, receiver signal strength indication (RSSI), single- and multi-carrier power amplifier linearization/control loops, point to multipoint broadband access, point to point high capacity QAM radio links, cellular repeaters, and RF instrumentation equipment.

Analog Devices unveiled the AD8362, a radio frequency integrated circuit (RF IC) designed to measure complex modulated waveforms common to all next generation wireless infrastructure equipment. The AD8362 performs a precise root-mean-square (RMS) power level measurement, providing the user with an accurately-scaled, linear-in-dB output. These measurements are particularly challenging for the next generation cellular base stations employing 3G Code Division Multiple Access (CDMA), Wideband-CDMA, and 2.5G Enhanced Data Rate for GSM Evolution (EDGE).
