A highly integrated GPS RF Front End which uses a single conversion stage
employs an image rejection mixer stage to eliminate the need for an image
reject RF bandpass filter. Also a relatively high sample rate A/D is
employed which allows a timeless monolitic IF Filter to be used. The
disclosure also discusses a GPS Front End topology that is easily
integrated from industry standard building blocks. With the broad
variation in potential receiver designs, the present invention includes
some specific receiver topologies that lend themselves to a high level of
integration. The specific designs presented here are comprised of
industry standard building blocks and functions that have been described
elsewhere in the related art.
