Abstract
An AESA (Active Electronically Scanned Array), including: a PCB (Printed Circuit Board) substrate having an obverse surface; TRMs (Transmit/Receive Modules) disposed on the obverse surface; thermal pedestals wherein each thermal pedestal includes a wall, having a wall height, including wall surfaces and one of the wall surfaces being a contact surface; and a TIM (Thermal Interface Material), having a TIM height, disposed between a respective contact surface of the thermal pedestals and the obverse surface. The thermal pedestals are discrete with respect to one another, the contact surfaces of the thermal pedestals are interspersed about the TRMs, the thermal pedestals do not contact the TRMs, the TIM is electrically and thermally conductive, and the wall height plus the TIM height is sufficient to suppress resonances of the TRMs below a frequency greater than the Tx and Rx frequency bands of the TRMs.
