I/O ports. Ground vias are used along single ended RF IO traces. Optimal via spacing is 1/10 of a wavelength, but that spacing can vary
somewhat due to practical layout considerations.

RF IO baluns are spaced and aligned to reduce magnetic coupling from the structures in the balun package. Care must also be taken to
reduce cross talk over shared grounds between baluns. Another precaution taken involved placing and orienting SMA connectors to
minimize connector to connector coupling between ports.
