使用左右手混合傳輸線設計威爾京森功率整合線性放大器

Abstract

本論文首先敘述使用集總元件以及微帶線設計左右手混合傳輸線，並配合相位要求，設計威京森功率分配器。接續使用NE32684電晶體設計一線性放大器，最後結合兩只放大器及兩只威京森功率分配器，設計2.1GHz功率整合線性放大器，論文內容包含各電路之原理、設計、製作及實驗量測。

This thesis presents the design of a compact-size Wilkinson power divider by using composite right/left-handed transmission line (CRLH TL) which is composed of lump elements and microstrip lines. The phase of the CRLH TL is achieved to fulfill the required frequency response of Wilkinson power divider. A linear amplifier is designed by using NE32684 transistor. Finally, a 2.1GHz Wilkinson power-combined linear amplifier is implemented by integrating two Wilkinson power dividers using CRLH TL and two linear amplifiers. Basic theory, design, simulation, implementation and measurement results are described.
