RESUMO

A novel technique of pulsed microwave waveform generation has been developed. It is based on the mixture of two arbitrary signals, an ultra-fast pulse train and a microwave carrier, all generated from different sources and combined in the optical domain in order to preserve the spectral and temporal features as much as possible. The technique s concepts and the setup used for the experimental validation have been presented. The obtained results are discussed and compared to the pulsed microwave signals generated by a modern commercial microwave generator. The main components are also characterized and proposals of improvements have been presented. The waveform resulted from this developed technique reached the expected results
