摘要： Embodiments of a radio frequency (RF) circuit provide translational filtering in accordance with an input impedance response that is an impedance image of a reactive circuit impedance response from a poly phase reactive circuit. The RF circuit may include a first mixer circuit that provides a first frequency offset for the impedance image and a second mixer circuit that provides an additional frequency offset. Accordingly, the second mixer circuit may allow for adjustments to a total frequency offset of the impedance image. The second mixer circuit may also be configured so that the impedance image rejects a negative frequency impedance response of the reactive circuit impedance response.
摘要翻译： 射频（RF）电路的实施例根据作为来自多相无功电路的无功电路阻抗响应的阻抗图像的输入阻抗响应提供平移滤波。 RF电路可以包括为阻抗图像提供第一频率偏移的第一混频器电路和提供附加频率偏移的第二混频器电路。 因此，第二混频器电路可以允许调整阻抗图像的总频率偏移。 第二混频器电路也可以被配置为使得阻抗图像拒绝无功电路阻抗响应的负频率阻抗响应。
