i'm entering the AD8361 with a AM signal (1.5 upto 30MHz) 1kHz modulation tone 80% depth. Then i connect 1nF between the pins 1 to 6 because the input signal could have in general 200kHz bandwidth and i would have like to see the output signal at VRMS pin (so could even not be an AM signal). I was expected to have at that pin (pin 7) something that should look like a squared sinusoid, but what i have seen is a sinusoid (so the modulation tone) as i had an envelope detector.
Is this behaviour correct? If this were an rms true detector shouldn't i have seen a squared wave?
