I want to use an amp to amplify signals before they are sent into AD9653, and also between them is a BPF(-5db insertion loss) to filter out-of-band noise. So the output of this amp should be 15dbm(1.3V) + 5db = 20dbm. And also, in order to take full advantage of the 16 bits precision, the out-of-band noise should be about 96db smaller than the signal. So I think I need an amp with very high linearity.
The magnification is supposed to be higher than 25db. Since the input signal is about -5dbm.
Could you give me some suggestions about choosing an AMP?
