碩士 === 國立高雄第一科技大學 === 電子與資訊工程研究所 === 98 === ABSTRACT
Base on theoretical derivation of direct RF to digital (RF2D) conversion, we analyze gain and bandwidth requirements for RF2D circuit realization. A QPSK example is illustrated and implemented based on the derivation and analysis. From the Matlab Simulink model, we achieve 100MHz baseband frequency and 200 Mbps throughput assuming 2.5GHz RF carrier modulated with QPSK under WiMAX wireless technology. The RF2D test chip mask layout simulation (post-layout simulation) also shows the same performance. We prove that with the derived specification, the RF2D dramatically saves circuit area and power consumption since no need of ADC, DSP, neither down converter to perform functions of the whole wireless receiver. Therefore, the RF2D conversion is proved achieving the ultimate objective of software defined radio (SDR).
Keywords: Direct RF to Digital Conversion, Software Defined Radio, Digital Modulation and Demodulation, WiMAX, Wireless Receiver.
