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.
