目前,在混频器市场,要选择一款带宽较宽、高线性度和低噪声的混频器,电子设计工程师往往需要在有源混频器与无源混频器之间作出选择,前者在宽带性能方面表现优秀,但无杂散动态范围却表现一般。后者虽然在无杂散动态范围性能方面表现较佳,但工作带宽却不如前者。因此,在现有的接收机设计中,为了满足 Currently, in the mixer market, to choose a wider bandwidth, high linearity and low noise mixer, electronic design engineers often need to choose between active mixers and passive mixers, the former Excellent performance in terms of broadband performance, but spurious dynamic range but performance in general. The latter, while performing better on spurious-free dynamic range performance, is not working at the same bandwidth. Therefore, in the existing receiver design, in order to meet
