Design approach and spacecraft EMI test methodology for high power communication spacecraft

Modern communication spacecraft present challenging Electromagnetic Interference (EMI) problem due to high power generation (10 kilowatts and higher), and requirements to accommodate various communication payloads from UHF to Ka frequencies on the same platform. Such spacecraft are designed to stringent military specification to achieve electromagnetic compatibility (EMC). This paper describes EMI design approach and test methodology which were successfully implemented on one such satellite program to ensure compliance with stringent EMI requirements using best commercial practices.
