AD607 does NOT have a "quadrature detector". It has an "I & Q demodulator".
BIG difference. You must read the datasheet and app notes to use it
correctly. It is capable of demudulating many types of modulation. [typo

My mistake, I undersand. But datasheet says nothing more exept "it is
possible to detect ssb with ad607"

Thanks
