利用屏蔽介质棒谐振器的TM/sub 010/主模,构造了新型小型化带通滤波器。下一个高阶模存在于TM/sub 010/模以上的倍频程频带处。结果表明,没有杂散响应的倍频程带,6%或更大的相对带宽,和10 ppm//spl度/c或更小的频率稳定度可以实现这些滤波器。预期插入损耗对应于在6 GHz下测量的2800的无载Q。
New types of miniaturized bandpass filters have been constructed by using TM/sub 010/ dominant mode of a shielded dielectric rod resonator. The next higher order mode exists at an octave frequency band above the TM/sub 010/ mode. It is shown that no spurious response in the octave band, relative bandwidth of 6 % or more, and frequency stability of 10 ppm//spl deg/c or less can be realized for these filters. The insertion loss corresponding to the measured unloaded Q of 2800 at 6 GHz is expected.
