Help! Advice on getting into the area of RFIC!

HI! I am a student in my first year of graduate study and I want to get into the field of RFIC. Rightnow, I am reading the book Design of Analog CMOS IC by Behzad Razavi and The Design of CMOS RFIC by Thomas,H Lee. I think it seems that analog IC design is the foundation for RFIC design, but it takes really a lot of time to learn the analog IC design.
Is that right for me to focus both on the two books equally? cause I have really a limited of time.
By the way, could anyone give me some tips on my current learning,please? thanks so much! cause I am really a freshman in this area.
