hi everyone

I’m looking to implement an amplifier in the range of 100KHz to 2MHz to obtain amplitude and phase information.

Whether the AD630 will be ok for this frequency range or is there another device out there that is better?

If the AD630 is ok, which diagram I should follow, the circuit diagram 9a Gain-of-One balanced modulator or diagram 14 Lock-In amplifier to obtain amplitude and phase?
