| 发明名称 | TM mode RF filter having dielectric rod resonators with cylindrical parts of different diameter | ||
| 摘要 | The invention relates to a dielectric resonator rod in a transverse magnetic mode radio frequency filter comprising a first cylindrical end part (10) of a first diameter (D1) and a second cylindrical end part (20) of a second diameter (D2). The first diameter is different than the second diameter and the first cylindrical end part (10) is connected via a third intermediate part (30) to the second cylindrical end part (20). The third intermediate part (30) comprises a tapered outer circumferential surface connecting the first cylindrical end part (10) to the second cylindrical end part (20). | ||
