In chapter seven, a power amplifier using power combination technology is presented. 最后介绍利用功率合成技术制造毫米波功率放大器的方法。
The present paper presents a new method for restraining the light lasing of the travelling-wave optical amplifier by means of the combination of dip and taper angles in the structure of the device. 文章讨论了行波管放大器的非线性特性,研究了预失真和前馈线性化技术,提出一种利用预失真与前馈法相结合的新方法来对行波管进行线性化。
It consists of two parts : a transconductance amplifier and a transresistance amplifier formed by resistor feedback. The combination of these two amplifier forms a voltage amplifier with low output impedance, and the pole at the output node is hardly affected by the loading capacitor. 它由两部分组成:前面为跨导放大器,后面则是由电阻反馈形成的跨阻放大器,两种放大器的组合构成了具有高输入阻抗、低输出阻抗的电压放大器。
The four stages power amplifier is using tree type network for power combination. Four paralleled transistors are matched with load-pull impedance at the last stage for maxium output power. 功率放大器采用4级放大,树状功率合成网络,末级是4个晶体管并联并按负载牵引匹配,在单片上获得尽可能大的功率输出。
