Take the circuit of figure 29 in the chip manual. I feel should be 7 feet to output a as carrier frequency rectangular wave, but only when you work in the low frequency 7 feet is rectangular wave, increase frequency waveform after peak can decrease the distortion. That's the phenomenon when I was using it.

What is the shape of the 7 legs of ad630 working on the modulator? And how many carrier frequencies can we get? I hope to get your answer. thank you

 

The waveform of the 7 feet when the carrier frequency is 300HZ

 

The waveform of the 7 feet when the carrier frequency is 800HZ

 

The waveform of the 7 feet when the carrier frequency is 2k

 

The waveform of the 7 feet when the carrier frequency is 2k
