High path loss and availability of wide bandwidth make
mm-waves an ideal candidate for short range, high data
rata communication. We propose a novel integrated chip
solution for wireless MRI where-in the transceiver uses
mm-wave (60GHz) as radio frequency carrier. ON-OFF
keying (OOK) modulation for data transmission enables
the transmitter to support data rates from 38Mbps to
2.45Gbps at a distance of 10cm while consuming 260W to
11.9mW of DC power. Highly directional, linearly
polarized, on-chip dipole antennas, placed orthogonally
results in a significant reduction in cross-talk between
multiple transceivers thus leading to a highly scalable
solution for wireless MRI.
