Rf Peak Detector. [5], revealing the difficulty of ensuring accuracy at even mode

[5], revealing the difficulty of ensuring accuracy at even moderately-low input levels; more complicated circuits attempting mathematical corrections do improve detector slope, but not necessarily accuracy [6]. Peak detectors also used to Introduction This section describes how a signal is processed by a Transimpedance Amplifier (TIA) , Analog-to-Digital Converter (ADC), and Half-Band filter (HB), and how this affects the triggering of analog and HB peak detectors. \\n I have two signals (demodulated sine waves) from an AD630, where the peak of the signals represent the value I need to measure. RF power detectors parameters, data sheets, and design resources. This is shown in Figure 2. 4 GHz signal do you want to include in your measurement (harmonic content is the only reason a peak detector circuit would give a result that isn't easily calculated from a power measurement, so you must have an answer I modeled the peak detector circuit in TINA and put an NPN transistor across the capacitor and drove it with a 2usec +5V pulse. This peak detector tracks the output voltage of a LNA/VCO and the measured signal is used to tune the LNA/VCO to the desired frequency. the input photo detector pulse train was a 3V, 200nsec wide pulse followed 40 usecs latter by a 1 V 200nsec wide pulse The result was worryingly good with very little voltage droop. This is achieved by peak detector circuit. S.
