Hello , im beginer in alectronics , and i designed a PCB using an AD8338
I'm using it in single ended without the AGC, and when i try to analyse the output of the VGA using an oscilloscope i dont have any signal . for some reason the ad8338 seem to produce a square wave that change in width when changing the gain (around mid-gain) at max and min gain, I got nothing at all (also append when there is no signal in input) could i have some advice of what i am missing or why i get this behaviour , i cant find a way to get any signal trough. Thanks in advance and sorry if there is some obvious mistake.
