A glass substrate architecture for mounting RF components may be configured for heat dissipation. Existing millimeter wave radiofrequency (RF) systems mount the radiofrequency integrated circuits (RFICs) on a printed circuit board on the opposite side of a heat sink, making it difficult to dissipate heat away from the RFICs during operation.
