Patent ID: 7542727

Claim:
A method of wireless communication in a wireless communication device, the method comprising the steps of: receiving a plurality of signals signal on a dual band antenna, wherein the signals include a first communication signal, a second communication signal and a global positioning system (GPS) signal centered at approximately 1575 MHz; coupling the signals to a diplexer; filtering the signal into one of a first band signal and a second band signal using the diplexer, wherein the second band signal includes the GPS signal; coupling the filtered first band signal to a first band duplexer; coupling the filtered second band signal to a GPS switching module that is configured to selectively couple the signals signal from the dual band antenna to one of a GPS module and a second band duplexer; if the filtered second band signal is a GPS band signal centered at approximately 1575 MHz, then switching the GPS band signal to the GPS module that includes an impedance matching circuit; impedance matching the received GPS signal with the impedance matching circuit tuned for the GPS band; amplifying the GPS signal with a GPS low noise amplifier (LNA); and if the filtered second band signal is not the GPS band signal, then switching the filtered second band signal to the second band duplexer.
