I thought this was an illuminating article on what some of the design considerations are for RF equipment with integrated SDR. Some points are obvious, such as antennas require hardware. Others are somewhat obvious, such as that PAs still need to exist separate from the DAC. The article then moves to discuss more fundamental limits on mixed-signal integrated circuits and why LNAs and ADCs aren't going to be on the same chip, and why sampling can't replace analog bandpass filters.
