RMS Responding Power Detectors
Recognized as the pioneer and leader in RF detectors, Analog Devices offers a broad portfolio of high performance logarithmic amplifiers and TruPwr™ rms responding detectors. ADI logarithmic amplifiers measure signals up to 100 dB dynamic range, from dc to microwave, and accuracies of ±0.2 dB, and are well-suited for both RSSI and transmit power level detection. The TruPwr rms detectors address the challenge of measuring complex waveforms found in spread spectrum CDMA/W-CDMA and higher order QAM modulation systems and provide an accurately scaled dc voltage, which is the rms equivalent of the input waveform.
