| Summary: | 碩士 === 國立臺灣科技大學 === 工程技術研究所 === 83 === The object of this article is the design of microwave broad-
band amplifier using microstrip line.The method of design is to
use TOUCHSTONE Matching the gain which we want. Then, using the
tunning method flattens the gain to achieve the goal. When a
single-stage amplifier is designed, we find that the input and
output VSWR is too large. We use the type of balanced amplifier
to achieve better goal. We use the transistor of FHX35LG to
design a amplifier of 2-4 GHZ with gain of 12 Many elements
cause some differences between simulation and experiment. One
goal of this article is to minim- ize the differences. In this
article, we actually minimize the differences between them by
changing the length and width of mi- crostrip line. On the
whole article, we use many figures. we ex- pect that the
readers can understand microwave amplifier deeper depending on
the comparison between the figures. Figures are easier.
