error with AD8001JR

sir:

    I use the AD8001JR to configure a Gain=1/16  circuit, in which I set Rf=806 ohm, while Rg=12.7k. The simulation is all right.When I provide the circuit with a 50MHz sinewave, the circuit fail to implement a gain of 1/16. In this circumstance, the output and input sinewave is almost with the same amplitude, while the ouput sinewave change the shape a litte. The oscilloscope picture is in the attachment.

 

what is the reason for this error of the circuit?
