Hello Dave,
I hope all is great with you.
Based on your requirements, you are correct, the AFT05MS031N device is a great option for your design. You may also consider the AFT05MP075N device.
What do you mean with “get the quote”? I do recommend to request more information to your local distributor.
Note that you can download the S-Parameter or ADS/AWR model from the webpage in case they are useful for you.

Regards,
David
