Connection Design between T/R Modules and Wave-control Units Applied to Space-borne Radars

Connection between T / R modules and wave-control units is very important to performance of the active phased array radar. Miniaturization,light-weight characteristic and high reliability of space-borne radars put forward higher requirements for connections between electronic devices. In this paper,a connection method between T / R modules and wave-control units applied to space-borne active phased array radars is put forward.By reasonable distribution of devices,design of connection cable,structural design of the fixing board and optimization of assembly techniques,an effective and highly reliable connection between T / R modules and wavecontrol units is achieved,which meets the miniaturization and light-weight requirements of space-borne radars.The effectiveness of this method has been verified by application in real space-borne radar.
