TRF3702 DAC5687 on separate PCBs?

Other Parts Discussed in Thread: DAC5687, ADS5500

Hi,

I am starting on a design for a digital radio using the DAC5687 + TRF3702 for the transmit chain and the ADS5500 + a demodulator for the receive chain. The baseband processing will be done in an FPGA. We have built a working prototype using evaluation boards already and now we are starting to work on our own hardware design. We plan to implement the design on two separate PCBs - a baseband board and an RF board that will be stacked to make the design more compact. I am writing to ask for advice on how to partition the parts - is it typical, advisable, not advisable, etc., to put the TRF3702 on a separate board from the DAC5687 with connectors between them? Or should the DAC and ADC go on the RF board with the digital signals going over connectors? Are there any comments on how others have done this?

Best regards,

Russ
