| 摘要: | 為了提供人類更大的便利性，無線傳輸已成為未來科技發展的主流技術。在此潮流下，符合個人式無線網路架構的藍芽/超寬頻通訊協定也因而誕生。藍芽無線傳輸技術具有低功率、低成本及幾近成熟的模組整合技術等優點。超寬頻在無線個人區域網路中是一個具有吸引力的新技術，其利用頻帶範圍3432MHz 到10296MHz 進行高速傳送資料。而上述的這些特點都是用於發展次世代藍芽的優勢。為提升台灣在國際的競爭優勢，在本研究中，我們擬提出開發用於射頻被動模組中的次世代藍芽系統中的雙工器。該雙工器會利用半導體製程技術實現於高介電陶瓷材料（K=9.8 或36）板上方，以實現微小化及高品質因素的頻率響應。該雙工器藍芽頻段的規格為：中心頻率制訂為2.44175 GHz、頻寬為83.5 MHz、S21 小於 -0.1dB、2.7-11 GHz 需低於-40dB、熱漂移係數控制在±5ppm/oC 以內。該雙工器超寬頻段的規格為：中心頻率制訂為8.3 GHz、頻寬為4.6 GHz、S21 小於-0.1±0.05 dB、 1-5.8 GHz 需低於-40dB、通帶內之群時延約0.1-0.3 ns、熱漂移係數控制在±5ppm/oC 以內。除此之外，兩個頻段之間的阻隔度需設計低於-40dB 以下。總而言之，本計畫將結合微波工程、電磁理論、射頻元件設計與高頻量測技術等跨領域之知識背景來完成一具有前瞻性之基礎科學與產業技術應用之研究。In order to provide all human beings a more comfortable life, wireless communication has become one of the most important technologies for the future. The traditional local area network (LAN) has become into wireless personal area network (WPAN) gradually. Under this trend, wireless personal area network structure-bluetooth/ultra-wide band (UWB) communication has been appeared. Bluetooth wireless communication technology has several advantages such as low power, low cost and maturity technology with the integration of Bluetooth module. Ultra-Wide Band system is a new and attractive standard technology of wireless personal area network, having the frequency range from 3432 MHz to 10296 MHz to process high speed data transmission. Above advantages are the important characteristics to develop a next generation bluetooth system. Therefore, we want to provide a project to study a novel diplexer of the RF passive modules used for next generation bluetooth system. The diplexer, realized on high dielectric ceramic substrate (K=9.8 or 36) by using semiconductor fabrication technique, achieve miniaturization and high quality frequency response. The high quality diplexer can be applied for bluetooth band and ultra-wide band. The specifications of the diplexer at bluetooth band are: center frequency of 2.44175 GHz, bandwidth of 83.5 MHz, S21 less than -0.1 dB, suppression of -40dB from 2.7 to 11 GHz and thermal shift coefficient of ±5ppm/oC. The specifications of the diplexer at ultra-wide band are: center frequency of 8.3 GHz, bandwidth of 4.6 GHz, S21 less than -0.1±0.05 dB, suppression of -40dB from 1 to 5.8 GHz, group delay of 0.1-0.3 ns and thermal shift coefficient of ±5ppm/oC. Additionally, the isolation between two channels is more than 40 dB. In above all, the project will combine the general knowledge of microwave engineering, electrical and magnetic theory and RF device design to complete an advanced integrated research of basic science and applied technology. |
