We are using AD8370 VGA in one of our projects at 140MHz.Although,I went through the datasheet i was not able to find the IP3 behaviour and gain step resolution @140MHz at low gain mode and high gain mode. There are performance figures at 70MHz.
I request you to send me OIP3/IIP3 v/s gain stage plot and also gain step resolution plots @140 MHz at lowgain and high gain mode.
Awaiting your reply at the earliest.
Thanks & Regards,
