摘要： A bandpass filter has a combline structure having a plurality of cascaded nodes (503, 504, 506, 508 ). A plurality of nodes in the filter are connected both to resonant elements ( 514, 517 ) (a.k.a. resonators) and non-resonant elements ( 601, 604 ) (including elements having inductances and/or capacitances that do not resonate in a predetermined frequency band of interest). The resonant frequencies of the resonant elements may be adjusted, in order to adjust the location of the center frequency and/or the width of the passband of the filter. The characteristics of the resonant and non-resonant elements are selected such that the poles of the filter, when plotted on the complex plane, move substantially along the imaginary axis when the resonant frequencies are adjusted, without substantial movement along the real axis. The resulting bandpass filter has substantially constant losses and substantially constant absolute selectivity over a relatively wide range of bandwidths.

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。
