摘要： The present invention provides target devices such as filter units with at least one receiving channel with a stop surface that is electrically conductive and at least one cable with a connector assembly on a first end portion. The connector assembly includes a first member with an open channel. The first member is coupled to the end portion of the outer conductor with the free end of the inner conductor and the end portion of the dielectric extending through the open channel to reside forward of the first member. The first member resides in a respective one of the at least one receiving channel against the stop surface. The connector assembly also includes a second member with an open channel. The second member is slidably coupled to the first end portion of the at least one cable and presses the first member against the stop surface.

摘要： 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.
摘要翻译：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主耦合和相对带电容的主耦合，而第二对非相邻导体具有感性交叉耦合。第一和第二对有一个共同的导体。在第二对非相邻导体之间，没有提供相应的感应交叉耦合的直接欧姆连接。相反的电容式主耦合补偿了第一对相邻导体之间的感应主耦合的至少一部分。在线谐振滤波器能够提供一个或多个传输零点，而不需要在非相邻导体对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，更不复杂，并且更不易受损坏。
