Doublet Modular for Design of Microwave Filters
A novel doublet modular in filter design isintroduced in the paper.We can use the doublet modular inbandpass filters.Using the doublet modular,asymmetrytransmission zeros are created in the bandpass filter.We canlocate the two transmission zeros at one side of the passband orboth side of the passband.The doublet modular is demonstratedvery flexible by showing a number of coupling matrices ofcases.It is earlier to design higher order filters of highperformance by cascading such doublet modular.And theresponse of the filter will be improved.In this paper,zeroshiftingproperties of the filter with source and load couplingare also proposed,which is different from zero-shiftingproperties proposed in filters without source and load coupling.
