Web2 Single diode detector circuit A single Schottky diode detection circuit is shown in Figure 2. Bypass capacitor C is chosen to be 1 nF so that it has low ohmic capacitive reactance up to 6 GHz. Usually the diode-based detectors can achieve broadband performance. The diode itself will define the frequency range of the detector circuit. Web\$\begingroup\$ I don't think an analog peak detector has to "mark" something as a peak. It just outputs the voltage of the most recently tracked peak. The peak detector output depends on the time constant of the detector circuit versus the spacing of peaks in the input signal. Perhaps I am confused. greene county vo-tech
