Part Number: TRF3722
I have 4 DACs (DAC37J84) on a board and trying to connecting to 8 TRF3722 on another board. I looked at the TRF3722 EVM board, it is using 2 SMA connectors for the In-phase input and another 2 SMA connectors for the quad-phase input. Which means 1 TRF3722 will need 4 SMA. And if I have 8 TRF3722, i would have 48 SMA connectors for interconnection, which have way too many connectors..
1) What is the recommended interconnections between them to have reduction in the number of lines?
2) Can I use "high speed board-to-board connectors" to connect them as differential lines?
3) Or do I need to use balun at the DACs side to do single-ended and then balun at the TRF3722 to reduce the no of coaxial cables if I cannot use the high speed board-to-board connection?
I think that you should check out this TI Design (TIDA-00409). It should show how you can interface with the modulator without the SMA connectors, however you should note that in this design the modulator is being interfaced with the DAC38J84.
In reply to Abdallah Obidat:
The design constraint doesn't allow to place the DAC38J84s and the TRF3722 on the same board, unlike the eval module you showed. Hence, asking recommendations on some board-to-board connections?

In reply to Ag:
I think that you should be able to use "high speed board-to-board connectors" for your baseband signal, considering your frequency and bandwidth.
