Este artigo representa um oscilador de segundo harmônico de baixo ruído usando diodos Gunn mutuamente sincronizados. Uma tecnologia MIC multicamadas é adotada para reduzir o tamanho do circuito do oscilador. O oscilador consiste em diodos Gunn, ressonadores de linha slot e linhas de tira. Ao incorporar diodos Gunn nos ressonadores de linha de slot, um sinal de RF harmônico pode ser gerado com muita facilidade. As linhas de tira são usadas para o circuito de saída de combinação de potência. O formato do ressonador de linha slot é quadrado para atingir o baixo ruído de fase e a supressão de harmônicos indesejados. O oscilador de segundo harmônico é projetado e fabricado em banda K. A potência de saída é de +8.89 dBm na frequência projetada de 18.75 GHz (2f0) com ruído de fase de -116.2 dBc/Hz na frequência de deslocamento de 1 MHz. Excelente supressão do sinal de frequência fundamental indesejado (f0) de -33 dBc é alcançado. Além disso, o tamanho do circuito é reduzido em três décimos em relação ao circuito proposto anteriormente.

Abstract: This paper represents a low noise second harmonic oscillator using mutually synchronized Gunn diodes. A multi-layer MIC technology is adopted to reduce the circuit size of the oscillator. The oscillator consists of Gunn diodes, slot line resonators and strip lines. By embedding Gunn diodes in the slot line resonators, a harmonic RF signal can be generated very easily. The strip lines are used for the power combining output circuit. The shape of slot line resonator is square in order to achieve the low phase noise and the suppression of undesired harmonics. The second harmonic oscillator is designed and fabricated in K band. The output power is +8.89 dBm at the design frequency of 18.75 GHz (2f0) with the phase noise of -116.2 dBc/Hz at the offset frequency of 1 MHz. Excellent suppression of the undesired fundamental frequency signal (f0) of -33 dBc is achieved. Also, the circuit size is reduced by three-tenths relative to that of the previously proposed circuit.
