1.序言最近,人们对高频技术领域中的频谱扩展通信方式、高频脉冲传输、多路传输等宽带信号传输方式很感兴趣。这是因为采用以前的技术,确保通信线路畅通无阻是较困难的。尽管现状如此,随着信息处理技术的发展,每一通信线路的频带展宽,就更增加了上述困难。在这种现状下,也就要求高频放大器有更宽的频带。过去,在高频信号的处理上,多半习惯采用滤波器技术。所以,如何用较少的元器件,
1. Preamble Recently, people are very interested in wideband signal transmission methods such as spectrum spread communication, high-frequency pulse transmission and multiplex transmission in the high-frequency technology field. This is because it is more difficult to use the prior art to ensure that the communication lines are free from obstruction. In spite of this situation, with the development of information processing technologies, the bandwidth of each communication line broadens even more. In this situation, it also requires high-frequency amplifier has a wider frequency band. In the past, in the treatment of high-frequency signals, mostly used to filter technology. So, how to use fewer components,
