摘要： A coupling structure for coupling two resonant cavities, which may be dissimilar, based on providing a metallic surface, called here a guide surface, at an angle intermediate between the orientation of the magnetic field in the two cavities. The guide surface may be one surface of a non-rectangular window cut in a wall separating the two cavities or may be the surface of coupling screw piercing, at the intermediate angle, a rectangular window in a wall between the two cavities. In the non-rectangular window embodiment, an adjusting tuning screw is provided that screws into a notch in the guide surface. In the angled coupling screw embodiment, coupling is adjusted by providing that more or less of the angled coupling screw extends into the rectangular window. The coupling structure couples any two cavities having mutually orthogonal magnetic fields by providing the guide surface at an orientation so the magnetic field in each cavity has a non-zero projection onto the guide surface.

摘要翻译： 基于在两个空腔中的磁场取向之间的角度提供金属表面（这里称为引导表面）来耦合两个谐振腔的耦合结构，其可以是不相似的。 引导表面可以是在分隔两个空腔的壁中切割的非矩形窗口的一个表面，或者可以是联接螺钉的表面以中间角度穿过两个空腔之间的壁中的矩形窗口。 在非矩形窗口实施例中，提供了一种调节调谐螺钉，其被拧入到引导表面中的凹口中。 在成角度的联接螺钉实施例中，通过提供多或少的成角度的联接螺钉延伸到矩形窗口来调节联接。 耦合结构通过将引导表面设置在定向处而使具有相互正交的磁场的任何两个腔耦合，使得每个空腔中的磁场在引导表面上具有非零的投影。

摘要： A delay filter uses the dielectric mono-block triple-mode resonator and unique inter-resonator coupling structure, having smaller volume and higher power handling capacity. The triple-mode mono-block resonator has three resonators in one block. An input/output probe is connected to each metal plated dielectric block to transmit microwave signals. Corner cuts couple a mode oriented in one direction to a mode oriented in a second, mutually orthogonal direction. An aperture between two blocks couples all six resonant modes, and generates two inductive couplings by magnetic fields between two modes, and one capacitive coupling by electric fields. The input/output probes, coupling corner cuts and aperture are aligned such that all six resonators are coupled in the desired value and sign, so constant delay on the transmitted signal within certain bandwidth can be achieved. By connecting the input and output probes to the base printed circuit board, the delay filter is surface mountable.

摘要： The present invention incorporates triple-mode, mono-block resonators that are smaller and less costly. The size reduction has two sources. First, the triple-mode mono-block resonator has three resonators in one block. This provides a 3-fold reduction in size compared to filters currently used which disclose one resonator per block. Secondly, the resonators are not air-filled coaxial resonators as in the standard combline construction, but are dielectric-filled blocks. The coupling between modes is accomplished by the corner cuts. One oriented along the Y axis and one oriented along the Z axis. In addition, a third corner cut along the X axis can be used. Corner cuts are used to couple a mode oriented in one direction to a mode oriented in a second mutually orthogonal direction. Each coupling represents one pole in the filter's response. Therefore, the triple-mode mono-block discussed above represents the equivalent of three poles or three electrical resonators.

摘要翻译： 本发明结合了更小且成本更低的三模式单块谐振器。 尺寸减小有两个来源。 首先，三模式单块谐振器在一个块中具有三个谐振器。 与目前使用的滤波器相比，这样可以减小3倍的尺寸。 其次，谐振器不是标准梳状结构中的充气同轴谐振器，而是电介质填充块。 模式之间的耦合由角切割完成。 一个沿着Y轴定向，另一个沿着Z轴定向。 另外，可以使用沿X轴切割的第三个角。 角切割被用于将定向于一个方向的模式耦合至定向于第二相互正交方向的模式。 每个耦合表示滤波器响应中的一个极点。 因此，上面讨论的三模单声道代表三极或三个电谐振器的等价物。

摘要： A microwave coupler has a planar form with a transmission line segment oriented at an angle relative to a main transmission line. The planar form of the transmission line, such as in a printed circuit board, helps reduce the size and manufacturing costs for the coupler. When placed a prescribed distance from the main transmission line and oriented at an appropriate angle, the directivity and coupling factor requirements can be met precisely with minimal tuning. Where fine tuning is required, a tuning screw and resistor disposed adjacent to the transmission line segment are provided.
