Abstract:
1. A system for the coexistence between a plurality of wireless communication modules sharing an antenna, comprising: a wireless communication chipset, comprising: a first wireless communication module capable of transmitting and receiving first wireless communication signals; a second wireless communication module capable of transmitting and receiving second wireless communication signals; and a combine-separate unit capable of generating a first combined signal by combining the first and second wireless communication signals, and separating a second combined signal into the first and second wireless communication signals; a switching device configured to selectively transmit the first combined signal or receive the second combined signal; and a directional coupler having a first port coupled to the antenna, a second port connected to the first port via a first path for transmitting the first combined signal or receiving the second combined signal via the first path and the antenna, and a third port connected to the first port via a second path for transmitting or receiving the second wireless communication signals via the second path and the antenna.
