1. An apparatus, comprising:

  • a first mixer configured to frequency translate a first communications signal to pa first frequency using a first local oscillator signal to provide a second communications signal;

    a filter module configured to filter the second communications signal to provide a third communications signal; and

    a second mixer configured to frequency translate the third communications signal to a second frequency using a second local oscillator signal to provide a fourth communications signal,wherein the filter module is characterized by a first center frequency and a first frequency bandwidth corresponding to the first frequency, the second mixer being further configured to effectively frequency translate the filter module to a second center frequency corresponding to the second frequency while maintaining the first frequency bandwidth.
