    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。

    Abstract: Filters include a housing having an input port and an output port and a plurality of resonant cavities within the housing. Each resonant cavity may include a respective notch resonator. The filter may further include a bandpass filter that includes a plurality of bandpass resonators, the bandpass filter extending between the input port and the output port. The bandpass filter may replace a transmission line that is included in conventional filters.

    Abstract: A (TM01) dielectric resonator (200) has a metal housing, a dielectric insert (210), and a resilient element (218) located between one end of the dielectric insert and the housing. The resilient element ensures physical contact between the housing and both ends of the dielectric insert over the entire operating temperature range of the resonator, thereby compensating for differences in the coefficients of thermal expansion of the materials used for the metal housing and the dielectric insert.

    Abstract: Provided an in-line resonator filter (400) comprising a linear array of three or more conductors (410), the linear array comprising:
    a first pair of adjacent conductors (410(1), 410(2)) having inductive main coupling and oppositely signed capacitive main coupling;
    a second pair of non-adjacent conductors (410(1) and 410(3)) having inductive cross-coupling, it is an objective of the present application to further allow the altering of the coupling within the resonator filter, and thereby tune the overall transfer function of the resonator filter to be different from the filter's inherent transfer function. The object is achieved by a first tuning element (422(3) and (4)) that extends from a bottom of the ground plane (402) of the in-line resonator filter; and
    a second tuning element (420) that extends from a top of the ground plane (404) of the in-line resonator filter; wherein:
    the first and second pairs have one conductor (410(1)) in common; and
    at least a portion of the oppositely signed capacitive main coupling compensates for at least a portion of the inductive main coupling between the first pair of adjacent conductors (410(1), 410(2)).
