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.
