因为注入式正交场放大管的电子注电流能够连续地从零变化到最大值,且在这样宽的电子注电流变化范围内具有良好的电子注聚焦特性和高的工作效率,所以它很适用于多模工作的雷达发射机中。同时改变磁场强度和外加的电压,可大大地扩大高效率下的脉升范围。此外,采用降压收集极技术也能改进脉升工作。本文给出了一只设计在X波段、脉升为10分贝、峰值输出功率为1.5到15千瓦、带宽为10%的低相位噪声注入式正交场放大管的测量结果,文中还讨论了降压收集极和磁场转换的影响。
It is suitable because the injection current of injection quadrature field-effect transistor continuously changes from zero to maximum and has good electron injection focusing characteristics and high working efficiency within such a wide variation range of electron injection current In multimode radar transmitter. At the same time changing the magnetic field strength and applied voltage, can greatly expand the range of high pulse rate. In addition, the use of buck collector technology can also improve the pulse of work. In this paper, we present the measurement results of a low phase noise injection quadrature field-amplifier with X-band pulse decay of 10 dB, peak output of 1.5-15 kW and bandwidth of 10%. In this paper, Pressure Collector and Magnetic Field Transitions.
