摘要
由于传统星载行波管放大器设计完成后仅有连续波或者脉冲1种工作模式,且饱和工作点输出功率固定,因此提出1种新的兼容连续波和脉冲多种工作模式的空间行波管电源设计方法。通过此方法设计完成的行波管电源与多模式行波管集成多工作模式行波管放大器,具备连续波工作模式、低重频脉冲工作模式和高重频脉冲工作模式及在轨功率可调节功能;能够应用于通信、导航、数传及遥感观测卫星,使在轨可重构载荷成为可能。通过仿真测试,多模式空间行波管电源效率达到94%,重频范围覆盖连续波到10 kHz,输出功率在47~53 dBm范围内可调节。
Since there is only one working mode of continuous wave or pulse after the design of a traditional spaceborne travelling wave tube(TWT)amplifier is finished and the output power at the saturated working point is fixed,a novel design scheme for space TWT power supply is proposed,which is compatible with multiple working modes including continuous wave and pulse.The TWT power supply and multi-mode TWT designed through this scheme are integrated into a multi-mode TWT amplifier,which have functions of continuous wave mode,low repetition rate pulse mode,high repetition rate pulse mode and adjustable on-orbit power.As a result,it can be applied to communication,navigation,data transmission and remote sensing observation satellites,thus making the on-orbit reconfigurable load possible.Through a simulation test,it is found that the power efficiency of the multi-mode space TWT reaches 94%,the repetition frequency range covers the continuous wave up to 10 kHz,and the adjustable output power ranges between 47 and 53 dBm.
