Gain = 1+(Rf/R1)=1+(500/50)=11.
B.W= Fu/Gn = 1.7M/11=155kHz.
B.W= Fu/Gn = 1.7M/11=155kHz.

There is the solution:
Fc=Fu/Gn
Fu is the bandwidth of unit gain
Fc is the required Bandwidth=1.7MHz
Gn(NON-INVERTING BANDWIDTH)=(Rf+R1)/R1=(11)
Fc=1.7MHz/11=154.5kHz
Fc=Fu/Gn
Fu is the bandwidth of unit gain
Fc is the required Bandwidth=1.7MHz
Gn(NON-INVERTING BANDWIDTH)=(Rf+R1)/R1=(11)
Fc=1.7MHz/11=154.5kHz
