    Abstract: The present invention provides filter assemblies, tuning elements and a method of tuning a filter. A filter assembly includes a housing having a top cover, a bottom cover and at least one sidewall, the top cover, the bottom cover and the at least one sidewall defining an internal cavity, the housing configured to receive first through third radio frequency (“RF”) transmission lines; a top metal sheet mounted within the internal cavity that has a plurality of openings that form a first hole pattern; and a bottom metal sheet mounted within the internal cavity that has a plurality of openings that form a second hole pattern. The top and bottom metal sheets are vertically spaced-apart from each other in a vertically stacked relationship within the internal cavity. The top metal sheet and the bottom metal sheet each include at least one resonator.

    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: A bracket for mounting a device to support structure has (i) a first side and (ii) second and third sides that extend perpendicularly from opposite edges of the first side in the same direction, such that the second and third sides are parallel to each other. The bracket supports a first mounting configuration in which the first side is attached to a face of the device and the second side is attached to a plane of the support structure such that the side of the device is perpendicular to the plane of the support structure. The bracket also supports a second mounting configuration in which the third side is attached to the face of the device and the second side is attached to the plane of the support structure such that the face of the device is parallel to the plane of the support structure.

    Abstract: A bandpass filter has a combline structure having a plurality of cascaded nodes. A plurality of nodes in the filter are connected both to resonant elements (a.k.a. resonators) and non-resonant elements (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.

    Abstract translation: 带通滤波器具有具有多个级联节点的梳状结构。 滤波器中的多个节点既连接到谐振元件（例如谐振器）和非共振元件（包括在感兴趣的预定频带中不谐振的电感和/或电容的元件）。 可以调节谐振元件的谐振频率，以便调节滤波器的中心频率的位置和/或通带的宽度。 选择共振和非共振元件的特性，使得当绘制在复平面上时，滤波器的极点在谐振频率被调整时基本沿着虚轴移动，而不沿实际实质运动。 所得到的带通滤波器在相对宽的带宽范围内具有基本恒定的损耗和基本上恒定的绝对选择性。

    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.
