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. A plurality of the thermal pedestals are physically interconnected, 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 a Tx and Rx frequency band of the TRMs. |

Multi-layer filter, arrangement, and method for production thereof
A multi-layer signal filter includes at least three physical layers. Each layer has through going apertures arranged with an offset to apertures of at least one adjoining layer, each layer further has a filter channel opening for receiving signals to be filtered. The apertures are arranged along a perimeter outside the filter channel opening and the apertures are arranged with a central surface portion increasing the edge length of the aperture. |
