RMS Detectors

Description
The measurement of complex waveforms found in spread spectrum CDMA / W-CDMA and higher order QAM modulation systems has traditionally been a demanding challenge. Analog Devices has developed a range of TruPwr™ detectors that enable the measurement of these complex signals at RF frequencies. The TruPwr™ detectors provide the user with an accurately scaled DC voltage, that is RMS equivalent of the input waveform. Within the TruPwr™ range Analog Devices offers products applicable to both Wireless / Wireline Infrastructure applications and devices packaged in small footprint for portable applications.
