- 초록
- In this paper, a K-band tunable cavity resonator filter is introduced. The tunable filter uses a dual TE211 mode cavity to reduce the size of the filter. To improve the tuning range of a pseudo-low pass filter that uses short irises, dummy iris is introduced. To enhance selectivity at band edge, additional cavity is introduced. A transmission zero generated by the additional cavity is controlled by only the cavity. To extend the rejection band, we use interaction between TE211 mode and adjacent modes. We fabricate and test the two-cavity, three-transmission zero tunable filters to verify the design results.
