【摘要】 文中用MAFIA软件设计了一只X波段行波管,计算了其冷热参数。冷测模拟结果为:通带带宽35％(6．8GHz-9．7GHz),在27％的频率范围内其归一化相速差小于 0．04:热测模拟结果为:-1dB带宽18％(7．1GHz-8．5GHz),最大输出功率2．5kW,最大增益18dB,效率18．4 ％。模拟结果显示设计的耦合腔行波管其冷腔通带、输出功率、带宽、效率均满足设计指标。更多还原

【Abstract】 A simple technique to design and optimize CCTWTs was provided in this paper. An X-band CW-CCTWT was designed and it’s parameters of cold tests and heat tests were both calculated by MAFIA. The results show that its bandwidth is above 18.0%(7.1GHz-8.5GHz) and its fluctuating gain is under 1dB; at the same time its maximum output power reaches 2.5kW, and its gain is 18dB, and its efficiency is above 18.4%. All these parameters meet the aim of design.更多还原
