Neste artigo, discutimos um sistema de rejeição de imagens IF com largura de banda e frequência central variáveis. O sistema consiste em um par de misturadores de frequência multiplicados pela senóide complexa e um filtro analógico complexo. Ao empregar a complexa estrutura de salto usando a configuração OTA-C e a transformação de frequência do LPF normalizado, o sistema proposto é capaz de largura de banda variável e características de frequência central. As simulações SPICE resultam em mais de 43 [dB] de rejeição de imagem para larguras de banda de 6 [kHz] e 12 [kHz] a 50 [kHz] IF.

Abstract: In this paper, we discuss an IF image rejection system with variable bandwidth and center frequency. The system is consists of a pair of frequency mixers multiplied by the complex sinusoid and a complex analog filter. By employing the complex leapfrog structure using OTA-C configuration and the frequency transformation from the normalized LPF, the proposed system is capable of variable bandwidth and center frequency characteristics. SPICE simulations result more than 43 [dB] image rejection is achieved for 6 [kHz] and 12 [kHz] bandwidths at 50 [kHz] IF.
