Frequency agile magnetron plays an important role in the vacuum electron device. The frequency-agile technique is based on changing the structure of resonator by tuning elements. The mechanism was studied in detail. A ten cavity S band magnetron with frequency-agile was proposed. The modes of resonate were analyzed and the wanted mode π mode has good performance. The results of dispersion relation analysis show that the device can reuse the electrical parameters of the existing fixed-frequency magnetron, which can dramatically reduce the development and production costs. The tuning bandwidth is 48.3MHz and the output frequency is subject to sinusoidal modulation, which not only has great potential to be applied to tunable local oscillator in frequence-hopping communication systems, to microwave energy applications to improve heating uniformity and ports isolation as well.
