本文叙述一支用于空间系统的高效率、高可靠行波管的设计与研制。空间系统在发射过程中要受到剧烈的振动和冲击;空间系统能源的昂贵,要求它所采用的功放器件——行波管应具有高效率和高可靠的特性。该管的设计采用了相速负跳变和降压收集极技术,使其总效率达40%至42%,500兆赫带宽内的增益为36分贝。我们在借鉴国外技术的基础上,进行了部件和整管的结构设计,实现了空间行波管的可靠性。它不仅满足了空间环境模拟试验的各项例行要求,并在实际空间飞行中获得了验证。
This article describes the design and development of a highly efficient and highly reliable traveling wave tube for space systems. Space system in the launch process to be subjected to severe vibration and shock; space system energy expensive, requiring it to use the power amplifier device - traveling wave tube should have high efficiency and high reliability. The tube was designed with a phase-negative negative-trip and buck collector technology to achieve a total efficiency of 40% to 42% and a gain of 36 dB over a 500 MHz bandwidth. We learn from foreign technology on the basis of the structural design of components and the whole pipe to achieve the reliability of space traveling wave tube. It not only meets the routine requirements of space environment simulation tests, but also has been verified in real space flight.
