RMS Detectors

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. With TruPwr™ products Analog Devices offers power detectors applicable to both Wireless / Wireline Infrastructure applications, instrumentation and military equipment, and devices packaged in small footprints for portable applications.

  • ADL5504- 450 MHz to 6000 MHz TruPwr Detector
    ADL5504:450 MHz to 6000 MHz TruPwr Detector

    The ADL5504 is a TruPwr™ mean-responding (true rms) power detector for use in high frequency receiver and transmitter signal chains from 450 MHz to 6000 MHz. Requiring only a single supply between 2.5 V and 3.3 V, the detector draws less than 1.8 mA. The input is internally ac-coupled and has a nominal input impedance of 500 Ω. The rms output is a linear-responding dc voltage with a conversion MoreRead more
