【摘要】 本文针对皮秒级脉冲频谱,尤其是基于实验条件,针对直流成分较高的皮秒级Gauss脉冲的频谱及其脉冲抑制方法展开了研究,分析结果表明:当脉冲宽度小于100ps时,微波频段内的能量占比成指数形式增长;而微波传输线型器件寄生通带的存在,将加大电磁脉冲对其造成的干扰。基于此,文中给出了脉冲抑制滤波器的引入条件和具体列表,具体设计制造了附加高通负载的脉冲抑制新型滤波器。实验结果表明寄生通带内的幅值均小于-20dB,证实了该滤波器的有效性。更多还原

【Abstract】 In this paper,the spectrum of picosecond pulse is analyzed based on experiment conditions,especially for Gauss pulse whose direct component is relatively higher.The fact that the pulse’s energy ratio in microwave range increases exponentially as pulse-width decreasing under 100 ps is revealed.The intrinsic parasitic pass-bands will enhance pulses’ interference on the traditional microwave devices.Based on this,the conditions for introducing in pulse suppression are presented as a detailed table and a novel filter with a high pass load is fabricated.The experiment validated the filter and-20 dB attenuation is achieved in every parasitic pass-band.更多还原
