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.

Abstract: A multi-band wireless communication device includes a plurality of transmit paths outputting signals to one or more antennas and one or more power amplifiers coupled to the transmit paths. Each of the transmit paths is configured to transmit signals on a specific radio frequency (RF) band. The RF bands can include the Advanced Wireless Services (AWS) band and the Personal Communication Service (PCS) band. Passive filters, such as SAW, BAW or FBAR devices, having out-off-band low return losses are included in the transmit paths. The passive filter and phase shifters on each transmit path can be configured so that RF switching between transmit paths is not necessary and a single power amplifier can be used for the different RF bands. Significant cost, power and space savings can be achieved by reducing the need for RF switches and using a single power amplifier to amplify plural RF bands.
