[en] HIGH SPEED SEMICONDUCTOR AND FR-4 INTEGRATED WAVEGUIDE / [pt] INTEGRAÇÃO DE CIRCUITOS DE ALTAS VELOCIDADES POR MEIO DE GUIA DE ONDA SEMICONDUTORES E SUBSTRATOS FR-4

VANESSA PRZYBYLSKI RIBEIRO MAGRI 28 June 2013 (has links)
[pt] Este trabalho de Tese apresenta a pesquisa e desenvolvimento de conexões de ondas guiadas sobre substratos semicondutores (SiGe, GaAs). A integração de circuitos digitais através de guias S-SIWG (Semiconductor Substrate Integrated Waveguide) utilizando formato de modulação QAM é avaliada e destacada. Conexões internas aos chips e entre chips são associadas com o novo padrão Gigabit Ethernet 802.3ba operando na taxa de 100 Gbit/s estendendo-se a aplicações de 0,5 – 1,5 Terahertz. É também apresentada a pesquisa e o desenvolvimento de guias e dispositivos de microondas utilizando substratos de baixo custo e altas perdas (FR-4), substratos cerâmicos de alta constante dielétrica (Er igual a 80) e aplicações em subsistemas híbridos integrados. / [en] This work presents the research, design and development of guided waves connections in semiconductor substrates (SiGe, GaAs). The integration of digital systems using Semiconductor Wave Guides (S-SIWG) with QAM modulation formats are highlighted. Ultra-fast inter-chip and inner-chip connections are associated with the new Gigabit Ethernet IEEE 802.3ba standard at 100Gbit/s extended to (0.5-1.5) Terahertz domain. Additionally fiber glass substrates with high losses (Teflon/FR-4) and high dielectric ceramic substrates (Er equal 80) are also developed to be integrated with microwave devices, analog printed circuits boards and high Speed digital circuits and systems.
