摘要:	為配合發展具有高位元傳輸率的毫米波寬頻雙向收發機，本研究將利用積體電路製程，研發毫米波寬頻帶通濾波器以及低通濾波器。傳統的微波濾波器設計，多以四分之一波長或二分之一波長傳輸線為基本組件，因而佔有較大電路面積，並不適用於單晶積體電路，而一般小型化濾波器設計多局限於窄頻應用。本研究將以集總元件搭配平行耦合傳輸線，利用砷化鎵與金氧半製程開發小型化寬頻帶通濾波器，並以集總元件架構實現新式積體化低通濾波器，並進一步整合成毫米波寬頻雙向收發機單晶片，以達到大幅減小毫米波收發機模組體積，提昇效能，降低設計循環所需時間，以及製造成本的目標。對於本計畫所研發之各式毫米波濾波器，並將結合理論分析與實驗量測，進行其高頻操作下各種特性之詳盡探討。此外，亦將建立相關設計公式及等效電路模型作為設計工具，並探討應用於積體電路製程之最佳實施方式，以期得到最佳之系統效能。本研究成果將可作為微波與毫米波單晶片系統的關鍵技術。 ; In this study, in order to cooperate with the development of high data-rate millimeter-wave wideband bi-directional transceiver, the design of miniature wideband bandpass filters and lowpass filters in commercial semiconductor process will be investigated. Conventional microwave bandpass filter designs are usually based on transmission line sections of quarter-wavelength or half-wavelength long, such that the circuit sizes are too large and not suitable for integration on chip. In addition, most of the conventional compact bandpass filter designs are limited to narrowband applications. The goal of this research is to develop novel miniaturized wideband bandpass filters in GaAs and CMOS process based on the lumped-elements and coupled-line structure, and novel integrated lowpass filters using lumped-elements, so as to integrate with the millimeter-wave bi-directional transceiver single-chip. As a result, the advantages of circuit size reduction, performance enhancement, design cycle reduction, and cost minimization of millimeter-wave communication system can be achieved. The proposed miniaturized wideband bandpass filters and lowpass filters will be carefully examined, both theoretically and experimentally. Suitable equivalent-circuit models and design equations will also be established as effective design tools. The optimal circuit structure and circuit layout of these bandpass and lowpass filters will also be addressed so as to achieve optimal chip performance. They may serve as the basis for the future development of miniature microwave and millimeter-wave system on chips. ; 研究期間 9708 ~ 9807
