Looking for AGC IC with automatic gain control

I want to control the frequency output from 1Hz to 10Mhz . The higher frequencies (above 100KHz) show attenuation. So, i want to use AGC ic to make all the outputs constant.
I browsed for 2 days and found many ICs like CLC 430,520, but they do not suit my frequency requirement.
I finally got IC THS7001. But the gain adjustment is a kind of manual instead of automatic. We have to manually set the control inputs depending upon the frequency. I want this process to be automatic. Also, there are lot of factors to be checked while building eval board of this IC.
I want an IC which has AGC which is AUTOMATIC gain control.

Hi,
I think your circuit is called "ALC-automatic level controlling". so a searching can be more sucessfuller...
Good progress!

Apropos; NI`s CLC430 datasheet has an AGC Apll.-Circuit , refer pls for "FIG. 7. AGC Circuit" on it, & by CLC520 to "FIG.8. Automatic Gain Control (AGC) Loop"...
