I'm trying to build an instrumentation amplifier for frequencies around 10 MHz with a gain between 150 to 300. The circuit that i'm using is attached to this discussion. I'm using 3 amp ops AD8099 and the resistors were dimensioned for desired gain. The problem is that this circuit in breadboard is very unstable and i couldn't put it working. Should i buy some evaluaton boads of this amp ops? Should i use another and more stable amp ops for this propose? Should i add something in my circuit to put it working?
