5W射频宽带功率放大器的设计

在宽带放大电路的设计中,往往是以牺牲功率增益来换取宽频带的功率增益的平坦特性。本设计除了满足增益平坦和效率外,还考虑了波段转换的速度、体积、受环境影响的大小等要求。调试及试用表明,该放大器工作稳定,性能可靠,已成功应用于通讯实践。

In the design of broad band amplification electric circuit, often to gain broad band smooth characteristic of the power - plus is at the expense of the power- plus. This design not only contains the gain plus and the efficiency, but also has considered wave bandswitching speed and size and circumstance and so on. The debugging and practice indicated that, this amplifier work is stable, the performance is reliable, and this amplifier has successfully applied to the communication.
