Design of a C-band Highly Integrated Multi-functional Motherboard
The design scheme and critical technology of a 64 channel C-band high integration multi-functional motherboard are introduced in this paper.This integrated motherboard is applied to the front end simulation sub-array of active phased array radar.The power module,wave control module and chip T/R component are integrated into the sub-array motherboard by using the multi-layer printed board pressing technology.Through the simulation design of each function network performance and electromagnetic compatibility design,finally the integrated motherboard design are completed.The dimensions of the 64 channel C-band mother-board are 228 mm×308 mm×4.8 mm,the amplitude and phase consistency of the measured passive radio network channel is better than±0.1 dB,±1°,and the amplitude and phase consistency of the active receiving link channel is better than±1.4 dB,±5°.The integrated motherboard can realize the two-dimensional expansion of radar array size through block splicing.It is suitable for multiple layout schemes to avoid inefficient and repetitive design.
