Patent ID: 7376440

Claim:
A wireless communication device comprising: an antenna; a low noise amplifier (LNA) configured to amplify signals within a plurality of frequency bands comprising a first frequency band, a second frequency band, and a GPS frequency band; and a N-plexer connected between the antenna and the LNA, the N-plexer comprising: a first frequency receive filter configured to pass first signals received through the antenna within the first frequency band to the LNA and to attenuate at least some signals outside of the first frequency band; a second frequency receive filter configured to pass second signals received through the antenna within the second frequency band to the LNA and attenuate at least some signals outside of the second frequency band; a GPS frequency receive filter configured to pass GPS signals received through the antenna within the GPS frequency band to the LNA and attenuate at least some signals outside of the GPS frequency band; a first frequency transmit filter configured to pass first transmission signals within the first frequency band from a first transmit signal path to the antenna; and a second frequency transmit filter configured to pass second transmission signals within the second frequency band from a second transmit path to the antenna.
