Abstract :
This paper investigates the properties of a lossless bandpass ladder network composed of only two kinds of resonant sections consisting of lumped- and distributed-elements and gives the necessary and sufficient conditions for realization. These conditions can be regarded as a direct generalization of the necessary and sufficient conditions for LC bandpass ladder networks proposed previously
