Differential IF amplifier for transmitter

Hi,

I am designing an LTE transmitter using the two-step architecture. I need a differential IF amplifier after DAC output. The IF frequency is 164MHz, bandwidth is 20MHz, it will be followed by an IF SAW filter, then again a differential IF amplifier to drive the up-conversion mixer. I plan to use 50ohm for the impedance match.  I searched ADI website. It seems all differential IF amplifiers from Analog Device is designed with ADC interference in mind. Can I use those in my design?

 

Thanks,

 

George
