Hi
As you know, today fast conversion high resolution ADCs are common to use. today almost every IF part of a receiver is implemented using IF Sampling techniques. So IF engineers works change to Digital Signal Processing. But IF Chip Designers should designes High Bandwidth High Resolution Low Cost ADCs.
And About RF, i think we will see aday which we use ADCs to sample RF input. So RF Chip designers should use RF considerations in designing a High Bandwidth ADCs, not in "routing" a PCB. This issue is correct about receiver part but transmitter part problem such as designing a high performance power amp still remain.
