The Interference Blanking Unit is developed in order to ensure compatibility between the different units in aircraft for operation in various location while simultaneously broadcasting RF. The main function of the Interface Blanking Unit is to perform signal blanking in accordance with the priorities of in-vehicle receivers and transmitters in order to prevent the simultaneous broadcasting units from affecting each other due to electromagnetic radiation. In addition, it is designed in a reconfigurable and modular structure, taking into account the requirements that may be needed in the field. The configurable matrix feature processes the blanking signals received at high and low voltage levels by an FPGA with low latency and parallel processing capabilities, and directs them to the relevant signal blanking output, thus ensuring RF compatibility of simultaneous broadcasting units. IBU is designed to operate in harsh environmental conditions with respect to its passive cooling thermal management. IBU is designed in accordance with RTCA/DO-254, Design Assurance Level C.
