    摘要: A distributed amplifier has a plurality of amplifying sections which are connected between input and output lines comprising artificial transmission line sections. Input line attenuation compensThis invention was made with U.S. Government support awarded by the Department of the Navy, Contract No.: N00014-87-C-0157. The U.S. Government has certain rights in this invention.

    摘要翻译: 分布式放大器具有多个放大部分,其连接在包括人造传输线部分的输入和输出线之间。 输入线衰减补偿由连接到输入线的负电阻补偿电路提供。 补偿电路在输入线上提供负电阻,其基本上补偿沿输入线发生的衰减,从而显着增加分布式放大器的可用增益和带宽。 还可以提供负电阻输出线衰减补偿,例如通过利用共源共栅放大电路,该共源共栅放大电路包括第一共源极连接FET和第二共栅连接FET,共栅FET连接到输出线。 输出线衰减补偿的利用为增加分布式放大器的增益和带宽提供了进一步的能力。
