    • Circuits and methods for performing harmonic rejection mixing are provided. In some embodiments, the circuit comprises: a first amplifier that amplifies a received signal at a first gain; a second amplifier that amplifies the received signal at a fraction of the first gain; a mixer that receives a local oscillator signal having a first fundamental frequency and the first amplifier output, and outputs a first mixed signal; a second mixer that receives a second local oscillator signal having a fundamental frequency that is a multiple of the first fundamental frequency and the second amplifier output, and outputs a second mixed signal; and an output stage that receives the first and second mixed signals and outputs a sum of the first and second mixed signals.
    • 提供用于执行谐波抑制混合的电路和方法。 在一些实施例中,该电路包括:第一放大器,其以第一增益放大接收信号; 第二放大器,以第一增益的一小部分放大接收信号; 接收具有第一基频的本地振荡器信号和所述第一放大器输出的混频器,并输出第一混合信号; 接收第二本地振荡器信号的第二混频器,所述第二本机振荡器信号的基频是所述第一基频和所述第二放大器输出的倍数,并输出第二混合信号; 以及输出级,其接收第一和第二混合信号并输出​​第一和第二混合信号的和。
