Abstract:
A GPS-enabled, multi-band wireless communication device (WCD) uses a single antenna for receiving global positioning system (GPS) signals and for transmitting and receiving radio frequency (RF) signals in plural RF communication bands. The RF communication bands can include the Advanced Wireless Services (AWS) band, cellular band and Personal Communication Service (PCS) band. To achieve single antenna convergence, the WCD includes an n-plexer, an RF bypass path and an RF switch. The n-plexer is coupled to a GPS receive path and to transmit and receive paths for a first RF communication band. The bypass path bypasses the n-plexer and carries a second RF communication band. A switch selectively couples the antenna to either the n-plexer or the bypass path, depending on which RF communication band is being used.
