Abstract:
A wireless communication device front end includes power amplifiers, low noise amplifiers, and a distributed antenna system. The distributed antenna system includes antennas and an antenna coupling circuit. The antenna coupling circuit receives an outbound signal of a first wireless communication from a power amplifier and sends first and second components of the outbound signal to first and second antennas. The antenna coupling circuit also receives an inbound signal of a second wireless communication from a third antenna and sends the inbound signal to a low noise amplifier. The third antenna is a distance from the first antenna and from the second antenna such that, in air, the outbound signal is attenuated at the third antenna.
