摘要：A frequency conversion circuit is provided, to remove unwanted spuriousvariations in an output from a single side band mixer. In the frequency conversion circuit,
polyphase filters are connected to at least one of input and output ports of a single sideband mixer. The polyphase filters associate the spurious variation to be reduced in asquare wave signal with an extreme point in its own frequency region. The single sideband mixer mixes the signals supplied from the two polyphase filters to produce afrequency component having a frequency difference between both the signals.
