So, I just got my hands on a couple of MAX2832s (http://www.maxim-ic.com/datasheet/index.mvp/id/5160) and MAX2837s (http://www.maxim-ic.com/datasheet/index.mvp/id/5452). Didn’t know about the existence of these ICs until recently but they are definitely the most convenient help one can get in making a software defined radio.

Having your whole front-end on one IC has to be the best thing since sliced bread. The only things necessary (save for the supporting circuitry on the side and any baluns) would be to connect the baseband inputs and outputs to your DSP/FPGA (depending on your design).
