摘要:

为抑制EAST装置现场的电磁信号对低杂波系统运行的干扰,设计了一个交指型腔体滤波器,其中心频率为2.45GHz,带宽为0.245GHz。介绍了交指型腔体滤波器的设计思路和方法,利用高频电磁仿真软件HFSS仿真提高了设计效率和精度。

Abstract:

The lower hybrid current drive system will be interferenced by jamming signal in the EAST experiment site, so a interdigital cavity filter with passband centered at 2.45GHz is designed to repress the jamming signal.This paper gives the particular description of a theoretical analysis and practical design for interdigital cavity filter, and the filter is simulated by HFSS-software which greatly improves the efficiency and accuracy of the design.

Key words: LHCD, Interdigital cavity filters, HFSS simulation, Jamming signal
