The relationship between the immittance inverter co- e-cients and the coupling coe-cients is obtained under the non- resonating coupling condition. With the relationship and the deter- minant properties of the transformation matrix, the coupling matrix could be decomposed to many sub-matrixes for fllter designs. The physical signiflcance of the decomposition is discussed. Using this idea, a fllter can be decomposed to a number of sub-fllters, which could be connected by sections of transmission lines with the same characteris- tics kept.
