Joe,

How about an SDR Board with 2 ADCs, 2 DACs (for transmit beam
forming), FBGA FPGA and a Gigabit Ethernet this can be done easily as
I can adapt the Hermes PCB
to add the extra components, the size of the PCB would obviously increase.

The time consuming critical ground plane system is already sorted out,
I can give this a shot if you have the time for the software
development.

Regards,

Abhi
