You can use it just like any other op amp. You just need to be careful of the layout so it remains stable.
You will need an op amp with a gain bandwidth of at least 60 Mhz. Also check that the slew rate is high enough to reproduce your signal shape.

 

Max frequency is 10 MHz.
Gain is 3.
3*10 MHz=30 MHz. This is your Gain Bandwidth Product (GBP). Start looking for op amp that has GBP higher than 30 MHz.

That is how ronv came up with GBP of 60 MHz. He took the 30 MHz and doubled it to make sure your signal will fit the bandwidth.

So. Start digging through datasheets.

 

That is an exceptionally wide bandwidth for a single amp circuit. What is the application?
