Filters for combined radiotelephone/GPS terminals

A radiotelephone comprising:

• a radio front end that is configured to provide wireless radiotelephone communications using radiotelephone frequencies, and that is configured to receive global positioning satellite (GPS) signals from a plurality of global positioning satellites;
• a signal processor that is configured to determine a measure of location of the radiotelephone using GPS signals received at the radio front end when providing GPS mode operations and that is configured to process communications that are received at and/or transmitted from the radio front end when providing wireless radiotelephone communications;
• and
• a GPS mode filter that is configured to filter GPS signals received at the radio front end before being provided to the signal processor, wherein the GPS mode filter is configured to suppress energy at and/or below (1575.42−Δ) MHz, where 0<Δ≦16.42 MHz.

A method of providing radiotelephone communications at a radiotelephone comprising a radio front end that is configured to provide wireless radiotelephone communications using radiotelephone frequencies, and that is configured to receive global positioning satellite (GPS) signals from a plurality of Global positioning satellites, the method comprising:

• during GPS mode operations, suppressing energy at and/or below (1575.42−Δ) MHz for GPS signals received from the radio front end, where 0<Δ≦16.42 MHz;
• during GPS mode operations, determining a measure of location of the radiotelephone using the GPS signals having suppressed energy at and/or below (1575.42−Δ) MHz;
• and
• during wireless radiotelephone communications, processing communications that are received at and/or transmitted from the radio front end.
