Log Amps/Detectors

Find RF detectors that accurately detect and measure RF and IF signals in wireless systems. Recognized as the pioneer and leader in RF detectors, Analog Devices offers a broad portfolio of high performance logarithmic amplifiers and TruPwr™ RMS detectors. ADI's logarithmic amplifiers measure signals up to 100 dB dynamic range, from dc to 10 GHz, 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 RMS equivalent of the input waveform.
