Abstract
An integrated circuit (IC) includes a baseband processing module, a GPS receiver, and an RF section. The baseband processing module is coupled to process voice signals and data signals. The global positioning satellite (GPS) receiver module is coupled to process GPS signals. The radio frequency (RF) section id coupled to: transceive the voice signals as RF voice signals; transceive the data signals as RF data signals; and convert GPS RF signals into the GPS signals.
Claims20
A wireless device comprising:
- at least one antenna;
- and
- communications circuitry coupled to the at least one antenna and comprising:
- a radio frequency (RF) section configured to:
- receive an incoming RF signal;
- amplify the incoming RF signal;
- down convert the incoming RF signal to produce a down converted signal;
- high pass filter the down converted signal to produce voice signals and data signals;
- low pass filter the down converted signal to produce GPS signals;
- a baseband processor configured to process the voice signals and the data signals;
- and
- a global positioning satellite (GPS) receiver configured to process the GPS signals.

A wireless device comprising:
- at least one antenna;
- and
- communications circuitry coupled to the at least one antenna and comprising:
- a radio frequency (RF) section configured to:
- receive an incoming RF signal;
- amplify the incoming RF signal to produce a first amplified wide bandwidth RF signal, a second amplified wide bandwidth RF signal, and a third amplified wide bandwidth RF signal;
- notch filter the first amplified wide bandwidth RF signal to produce a first notch filtered RF signal having a center frequency corresponding to a carrier frequency of GPS RF signals;
- notch filter the second amplified wide bandwidth RF signal to produce a second notch filtered RF signal having a center frequency corresponding to a carrier frequency of RF voice signals and/or the RF data signals;
- subtract the first notch filtered RF signal from the third amplified wide bandwidth RF signal to produce notch filtered RF voice and/or RF data signals;
- subtract the second notch filtered RF signal from the third amplified wide bandwidth RF signal to produce notch filtered GPS RF signals;
- down convert the notch filtered RF voice and/or RF data signals into voice signals and/or data signals;
- and
- down convert the notch filtered GPS RF signals to produce GPS signals;
- a baseband processor configured to process the voice signals and/or data signals;
- and
