Abstract :
A novel filter topology which has two separate coupling paths: electric coupling path and magnetic coupling path between two resonators, is introduced to obtain the quasi-elliptical filter frequency response. Either magnetic coupling or electric coupling in two separate coupling paths can be dominant in the total coupling coefficient of the inter-stage resonators with the similar configuration but different positions of transmission zero points. Based on the proposed filter topology, examples of second-order and fourth-order filters have been designed and realized
