NTU-Array is a microwave interferometer which is made for probing the high red-shift objects by measuring the SZ effect. In Chapter 1, we introduce the scientific goals and a framework of NTU-Array. Chapter 2 and Chapter 3 describe the design and fabrication of optical link module. The benefit of transferring signals by the optical fiber is that the attenuation will not increase dramatically with distance. In Chapter4, we describe the measurement results of the gain equalizer and the optical link module. In Chapter 5, we summarize our work and present a future outlook.口試委員會審定書........................................1 致謝....................................................2 摘要....................................................3 Abstract................................................4 Table of Contents.......................................5 List of Figures.........................................7 List of Table...........................................9 Chapter 1 Introduction to NTU-Array 1.1 Scientific Goals...................................10 1.2 RF and LO Modules..................................11 1.3 IF Modules.........................................13 1.4 AD Converter and FX Digital Correlator.............15 Chapter 2 The Optical Link Module 2.1 Introduction.......................................17 2.2 Elements in the optical link module................17 2.3 Layout.............................................19 Chapter 3 The Gain Equalizer 3.1 Introduction.......................................21 3.2 Development of design equations....................21 3.3 Simulations and the layout.........................25 Chapter 4 Measurement Results 4.1 Measurement results of the gain equalizer..........31 4.2 Measurement results of the optical link module.....34 Chapter 5 Conclusions and Future Work 5.1 Conclusions........................................36 5.2 Future work........................................36 References.............................................38 Appendix A: A program that calculates parameters of the gain equalizer.........................................39 Appendix B: Data sheets................................44 B.1 Data sheet of the pre-amplifier....................44 B.2 Data sheet of the optical transmitter..............47 B.3 Data sheet of the optical receiver.................49 B.4 Data sheet of the post-amplifier...................526669298 bytesapplication/pdfen-US增益等化器光學傳輸Gain equalizerOptical linkthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/54506/1/ntu-96-R94222053-1.pdf
