Neste artigo são demonstrados pré-amplificadores distribuídos híbridos de 2 a 10 GHz usando dois e três amplificadores distribuídos de estágio único em cascata. Esses amplificadores produzem ganhos de potência disponíveis significativamente maiores do que os pré-amplificadores distribuídos convencionais usando o mesmo número de dispositivos ativos. Os resultados da simulação mostram a vantagem do pré-amplificador proposto em relação ao convencional. São apresentados os resultados medidos das duas configurações realizadas de pré-amplificadores usando dois e três amplificadores distribuídos de estágio único em cascata. Cada configuração mostra que o ganho de potência disponível pode ser aumentado aumentando a impedância característica entre estágios dos amplificadores distribuídos em cascata de estágio único. O ganho de potência disponível medido para dois estágios mostra uma melhoria de 18 dB para 20 dB, e para três estágios uma melhoria de 26 dB para 31 dB na banda de frequência de 2 a 10 GHz, à medida que a impedância característica entre estágios é aumentada de baixa para alto nível. São alcançadas perdas de retorno de entrada e saída melhores que -10 dB e isolamento de entrada-saída melhor que -55 dB no início da banda e melhor que -45 dB no final. Esta abordagem também fornece um bom desempenho de ruído medido de uma média de 4 dB na banda de frequência de 2 a 10 GHz para dois e três estágios em cascata. O atraso de grupo de ambos os amplificadores em cascata é medido. Seu desempenho plano prova a viabilidade desta abordagem, que é adequada para comunicação óptica digital e aplicações de pulso.

Abstract: In this paper 2-10 GHz hybrid-distributed preamplifiers using two and three cascaded single stage distributed amplifiers are demonstrated. These amplifiers produce available power gains significantly higher than conventional distributed preamplifiers using the same number of active devices. Simulation results show the advantage of the proposed preamplifier over the conventional one. Measured results of the two realised configurations of preamplifiers using two and three cascaded single stage distributed amplifiers are presented. Each configuration shows that the available power gain can be increased by increasing interstage characteristic impedance of the cascaded single stage distributed amplifiers. The measured available power gain for two stages shows an improvement from 18 dB to 20 dB, and for three stages an improvement from 26 dB to 31 dB across the 2-10 GHz frequency band, as the inter-stage characteristic impedance is increased from low to high level. Input and output return losses better than -10 dB, and input-output isolation better than -55 dB at the beginning of the band and better than -45 dB at the end are achieved. This approach also provides a good measured noise figure performance of an average of 4 dB across the 2-10 GHz frequency band for both two and three cascaded stages. The group delay of both cascaded amplifiers are measured. Its flat performance proves the viability of this approach which is suitable for digital optical communication and pulse applications.
