本文讨论了介质TE双模谐振滤波器。谐振器的电介质芯元件具有十字形状以提供双模操作。在中心形成两个通孔以改善杂散性能。由于孔被放置在两个正交谐振器之间，不同直径的选择导致模式之间的耦合。讨论了实现交叉耦合和与同轴空气腔谐振器耦合的概念。测量结果为一个单一的谐振器和两个耦合双模谐振器。所得到的四极点带通滤波器具有2022.5MHz的中心频率和28MHz的带宽。
In this paper dielectric TE dual-mode resonator filters are discussed. The dielectric core element of the resonators has a cross-shape to provide dual-mode operation. Two through-holes are formed in the center to improve the spurious performance. Since the holes are placed between the two orthogonal resonators, the choice of different diameters cause coupling between the modes. Concepts for realizing cross-coupling and coupling to coaxial air cavity resonators are discussed. Measurement results for a single resonator and two coupled dual-mode resonators are presented. The resulting 4 pole bandpass filter has a center frequency of of 2022.5MHz and a bandwidth of 28 MHz.
