This paper describes a high-Q X-band distributed Bragg resonator that uses an aperiodic arrangement of non-lambda/4 low loss alumina plates mounted in a cylindrical waveguide. An ABCD parameter waveguide model was developed to simulate and optimize the cavity. The dielectric plates and air waveguide dimensions were optimized to achieve maximum quality factor by redistributing the energy loss within the cavity. An unloaded quality factor (Q(0)) of 196,000 was demonstrated at 9.93 GHz.
本文介绍了一种高 Q 值的 X 波段分布式布拉格谐振器，该谐振器使用非 λ/4 低损耗氧化铝板的非周期性排列，安装在圆柱形波导中。为了模拟和优化腔，开发了 ABCD 参数波导模型。通过在腔体内重新分配能量损耗，优化了介质板和空气波导尺寸，以实现最大品质因数。在 9.93GHz 时，未加载品质因数（Q(0)）达到了 196000。
