É essencial, à medida que as larguras de banda das comunicações sem fio aumentam, avaliar os desequilíbrios entre as portas do mixer de quadratura, em termos de deslocamento de fase da portadora, desequilíbrio de ganho de QI e distorção de QI. Como é demorado separar a inclinação, a avaliação do desequilíbrio de ganho e do deslocamento da fase da portadora durante o teste é frequentemente realizada usando um valor composto, sem separação dos fatores de desequilíbrio. Este artigo descreve um algoritmo para permitir a separação entre desequilíbrio de ganho do misturador de quadratura, deslocamento de fase da portadora e inclinação. Como o tempo de teste é reduzido pelo método proposto, ele pode ser aplicado durante testes de produção de alto volume.

Abstract: It is essential, as bandwidths of wireless communications get wider, to evaluate the imbalances among quadrature mixer ports, in terms of carrier phase offset, IQ gain imbalance, and IQ skew. Because it is time consuming to separate skew, gain imbalance and carrier phase offset evaluation during test is often performed using a composite value, without separation of the imbalance factors. This paper describes an algorithm for enabling separation among quadrature mixer gain imbalance, carrier phase offset, and skew. Since the test time is reduced by the proposed method, it can be applied during high volume production testing.
