一种X频段50 kW高功放的设计
|
摘要
针对未来深空测控及其他航天器测控通信业务不断拓展的需求,设计了一种基于速调管方案的X频段连续波高功放。该方案采用了高效率低电源纹波的模块化高压开关电源、集中式液体冷却设备、串联与并联相结合的高功率谐波和收阻滤波器,以及高速可靠的控保措施,实现了在深空X频段连续波高功率输出的技术能力。测试结果表明:在规定的带宽内,输出连续波功率达到了50 k W,最高可达60 k W以上,第2、3、4次谐波及接收频段内信号的抑制能力等主要指标都达到了预期目标,整机散热效果理想;经长时间连续加电考机表明:设备考核指标和工作状态都稳定可靠。这将为我国深空探测技术的进一步发展、探测能力的进一步提高奠定坚实基础。
Based on the needs of development to deep space exploration and other space measure and control communication,a X-band continuous wave(CW)high power amplifier(HPA)based on the klystron scheme is presented,in which the high efficient low ripple modularized switch power,centralized liquid cooling equipment, high power filters and high speed reliable control measures are adopted,and the function of CW high power output in X-band deep space exploration is realized. The test results show that the CW output power can reach 50 k W(even up to 60 k W),the second,third and fourth harmonics are good and the cooling effect is ideal in the required bands. In addition,it shows that after long-time working the specifications of the equipment and working state are very steady and reliable which will provide supports for the further development of deep space exploration.
