We are using the ADL6012 Envelope Detector as a wake up threshold detector in an RF sensor application. Once the received pulses exceed an arbitrary threshold the rest of the RF repeater circuit is powered on to do its thing. Is it feasible to DC couple the outputs to the ADC inputs as long as the common mode voltages are within the appropriate range of both devices? Or do the outputs require AC coupling?
Configuring it this way would allow CW detection as well.
