A highly integrated GPS RF Front End, an interface thereto, and a GPS
receiver that incorporates the GPS RF front end, which uses a single
conversion stage employing 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 monolithic 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.
