摘要

為能滿足第四代行動通訊高資料流與高涵蓋率的需求，無論是WiMAX2或LTE-Advance在硬體網路架構上都必須以微型基地台(Pico-cell)甚至特微型基地台(Femto-cell)為基礎，因而導致基地台數量倍增以及同軸電纜高頻損耗等問題。本論文設計應用於無線射頻與光纖通訊整合技術(Radio-Over-Fiber, ROF)的寬頻收發模組，針對光強度調變與直接檢測(Intensity Modulation Direct Detection, IMDD)的光纖鏈路(Optical Links)深入研究，提出一種低成本寬頻帶的雷射直調式光收發機設計。操作頻率範圍為800MHz至2.6GHz，平均鏈路增益13dB(在光纖長度為零公里的測試條件下量測)。適用於分散式天線、分散式機房、光纖到大樓(Fiber to the Building, FTTB)以及光纖到路邊(Fiber to the Cabinet, FTTC)等系統。

To satisfy the high data rate and coverage requirements of the fourth generation mobile communication, the network structure must be deployed in pico-cell or even femto-cell for the WiMAX2 and LTE-Advance standards. This leads to enormous growth of deployed base stations, shielded and high loss of coaxial cable. This research designed a broadband RF transceiver for the Radio-Over-Fiber system, where the IMDD (intensity modulation direct detection) analog optical fiber links are focused. The optical direct modulation transmitter and the direct detection receiver have average RF link gain 13 dB from 800 MHz to 2.6 GHz and maximum NF 24.7 dB at 2.6 GHz.
The design methodology and measurement discussion are described in detail in the thesis.
