摘要：
A quadrature mixer with an LO input is provided. The quadrature mixer receives a signal having a frequency FLO and a signal input having a frequency FSIG and has an output that comprises an output impedance that is high at frequencies of [FLO-FSIG] and [FLO + FSIG] and low at other. A mixer coupled to the output impedance interacts with the output impedance such that an impedance presented at the signal input is high for signals at FSIG if FSIG is a predetermined signal frequency, and low at other frequencies.
