Patent ID: 7471936

Claim:
A receiver portion for selectively converting a GPS signal and a second RF signal to an intermediate frequency (IF) signal in a wireless handset, comprising: a GPS antenna configured to receive the GPS signal; a second RF signal antenna configured to receive the second RF signal; a control signal generator configured to generate a control signal; a band select switch connected to the control signal generator, to the GPS antenna, and to the second RF antenna, the band select switch configured to select one of the GPS signal and the second RF signal responsive to the control signal to determine a selected signal; a local oscillator (LO) connected to the control signal generator, the LO configured to generate an LO signal having a LO oscillating frequency responsive to the control signal, the LO oscillating frequency lower than a GPS frequency of the GPS signal when a frequency of the second RF signal is higher than the GPS frequency, the LO oscillating frequency higher than the GPS frequency when the frequency of the second RF signal is lower than the GPS frequency; and a mixer connected to the band select switch and to the local oscillator, the mixer configured to mix the selected signal and the LO signal to generate the IF signal.
