APPLICATIONS
Power and envelope measurement of W-CDMA, CDMA2000, and QPSK-/QAM-based OFDM, and other plex modulation waveforms RF transmitter or receiver power and envelope measurement
GENERAL DESCRIPTION
The ADL5502 is a mean-responding power detector in bination with an envelope detector to accurately determine the crest factor of a modulated signal. It can be used in high frequency receiver and transmitter signal chains from 800...
