Real-time FPGA implementation and measured performance of I/Q modulation based frequency synthesizer

Abstract

In this article, the design and implementation of mixed-signal frequency synthesis for wireless communications devices are addressed. The core of the synthesizer builds on digitally synthesized tunable low-frequency I/Q tone which is then shifted to the actual radio frequency range using I/Q modulation. An efficient real-time FPGA design of the digital… (More)
