| Abstract(in English) | In a direct-coupled resonator filter, which is constructed by cascade connection of resonators, the insertion loss at its center frequency can be estimated from unloaded Q factors by using a well-known formula derived by S. B. Cohn. However, the formula cannot be available for other circuit topologies, such as a transversal resonator array filter recently used as an equivalent circuit of multi-mode filters. To solve the problem, we have proposed a new insertion-loss formula for transversal resonator array bandpass filters. In this paper, the effectiveness of the proposed formula is verified from the viewpoints of both theory and application, thereby showing that the new insertion-loss formula has versatility, compared to the conventional one. |
