本文简述了并联型阶跃二极管倍频器的一般工作原理。文献[1]提供了并联型阶跃二极管的详细设计过程。我们工作与之不同的是:利用阻抗圆图进行了输入匹配回路的设计;为了提高倍频器的效率和稳定性,对1/4阻尼波产生器进行补偿。良好的结构设计和仔细的调整也是提高效率及稳定性所必不可少的。已经设计了输入频率为400兆赫的八次、九次、十一次和十七次倍频器,倍频效率可以分别作到30%、28%、25%、和10%。
This article briefly describes the general operating principle of a shunt diode stepper. Literature [1] provides a detailed design of the parallel step diode. Our work is different: the use of impedance circle diagram of the input matching loop design; in order to improve the frequency multiplier efficiency and stability, 1/4 damping wave generator to compensate. Good structural design and careful adjustment are also essential to increase efficiency and stability. The eighth, ninth, eleventh and seventeen multipliers have been designed with an input frequency of 400 MHz and the multiplier efficiency can be 30%, 28%, 25%, and 10%, respectively.
