碩士 === 逢甲大學 === 資電碩士在職專班 === 101 === The purpose of this dissertation is to implement a new integration of microwave filters and microwave amplifiers. Typically, there is a great gap between the design of a microwave circuit and its implementation or application. In addition, a single-circuit microwave circuit can be more easily implemented and is more competent to solve the problems caused by weak signals; however, an integrated system composed of multiple circuits may suffer from several flaws. This is an innovative study that proposed a new application. The proposed circuit can amplify TV signals that are transmitted through cables to provide better picture quality for TVs at homes with the help of microwave circuit integration, component selection, circuit layout design, and self-made components. This effectively solves the issue of inferior picture quality caused by the attenuation of long-distance signal transmission. Furthermore, the size of circuit boards and frames were successfully reduced to lower production costs through efficient design of the circuit board and adjustment of the transmission wire.
