A Novel 4×4 Full Switch Matrix Based on Clos Network
The Clos network structure is applied to the 4×4 full switch matrix for the first time,and the low temperature co-fired ceramic(LTCC)and double-pole,double-throw switch chips are integrated by multi-chip module technology.The full switc-hing function in a simpler topology is realized,and the shortcomings of the traditional single-pole,four-throw scheme with a large number of interfaces and complex wiring are overcome.The LTCC multilayer stacking process and specific chip interface are com-bined to realize feasible stacking structure and interconnection scheme.On this basis,C-band 4×4 switch matrix with excellent standing wave,good channel consistency and high isolation is developed.The implementation is simple and reliable,and is suit-able for other forms or higher frequency switch matrix design.
