Abstract
Abstract This article describes various housing design strategies of a complex receiver system to overcome EMI/EMC challenges for airborne system applications. Isolation of leakage energy between various RF/DC-DC converters/Regulators/pulsing blocks are the key target of this design to keep conductive and radiative emission minimum. Hence, complex receiver design has been segregated into various modules. Block level design is carried out using 3D EM simulator to assess the leakage. Then they are stacked together very tactfully within the specified area without compromising inter-channel/module interference between them and the form factor respectively. The super compact stacks are further channelized for RF, DC supply, controls etc. and protected them from any kind of interferences. Low cost flexi interconnects are made to interface various stacks to arrest unwanted high/low frequency leakages. Finally, receiver module is developed and tested over temperature and EMI/EMC successfully to establish the methodology.
