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.

AD8313 Output Voltage vs Input Amplitude
This calculator plots the response of the AD8313 in log (RSSI) mode and controller mode. By selecting the frequency range and correction factor, the slope and intercept are determined. This tool also calculates a simple LC match for the AD8313.
