Abstract: An in-line resonator filter has a linear array of three or more conductors. A first pair of adjacent conductors has inductive main coupling and oppositely signed capacitive main coupling, while a second pair of non-adjacent conductors has inductive cross-coupling. The first and second pairs have one conductor in common. Between the second pair of non-adjacent conductors, there is no direct ohmic connection that provides the corresponding inductive cross-coupling. The oppositely signed capacitive main coupling compensates for at least a portion of the inductive main coupling between the first pair of adjacent conductors. The in-line resonator filter is able to provide one or more transmission zeros without requiring any discrete bypass connectors that provide direct ohmic connection between pairs of non-adjacent conductors. As such, the in-line resonator filters can be smaller, less complex, and less susceptible to damage.

Abstract translation: 在线谐振器滤波器具有三个或更多导体的线性阵列。 第一对相邻的导体具有电感性主耦合和相反符号的电容性主耦合，而第二对不相邻的导体具有电感性交叉耦合。 第一和第二对有一个共同的导体。 在第二对不相邻的导体之间，没有提供相应的电感性交叉耦合的直接欧姆连接。 相反有符号的电容性主耦合补偿第一对相邻导体之间的电感性主耦合的至少一部分。 在线谐振器滤波器能够提供一个或多个传输零点，而不需要在成对的非相邻导体之间提供直接欧姆连接的任何分立旁路连接器。 因此，在线谐振器滤波器可以更小，更简单并且不易受损。
