发明名称 Low noise multi-stage type amplifier.
摘要 <p>particular, first- and final-stage amplifiers) are set so that an optimal signal source reflection coefficient GAMMA opt and S parameters are almost not varied by manufacturing variations. The lengths of source stubs (4, 13, 22, 31) connected to FETs of the amplifiers in the respective stages are optimally set in units of stages so that characteristics of the amplifier do not change due to the manufacturing variations, and a sufficient gain can be obtained. &lt;IMAGE&gt;</p>
