Coupling Matrix Decomposition in Designs and Applications of Microwave Filters
By
Progress In Electromagnetics Research, Vol. 117, 409-423, 2011
Abstract
The relationship between the immittance inverter coefficients and the coupling coefficients is obtained under the non-resonating coupling condition. With the relationship and the determinant properties of the transformation matrix, the coupling matrix could be decomposed to many sub-matrixes for filter designs. The physical significance of the decomposition is discussed. Using this idea, a filter can be decomposed to a number of sub-filters, which could be connected by sections of transmission lines with the same characteristics kept.
