Research Abstract

The purpose of this research is generation of Gbps class QPSK modulation signal using Interferometric Band Combine (InBC) technique. From the simulation results, we have found the new simple structure of the InBC. Using the developed experimental setup of dual branched InBC with 5GHz PLL and 100Msps DAC, we obtain the 200Msps signal (400Mbps with QPSK)
