One embodiment relates to a circuit for efficient wireless communication. The circuit includes an antenna interface module adapted to receive multiple frequency components via an antenna. Multiple reception paths stem from the antenna interface module, where different reception paths are associated with different frequency components. The circuit also includes multiple filter elements having inputs respectively coupled to the multiple reception paths. At least two of the filter elements cooperatively form a differential output signal based on their respective frequency components. Other methods and systems are also disclosed.

Radio frequency communication devices and methods

One embodiment relates to a circuit for efficient wireless communication. The circuit includes a communication port adapted to be coupled to an antenna feed. Multiple communication paths stem from the communication port, where different communication paths are associated with different frequency bands. Multiple phase shift selection circuits are respectively associated with the multiple communication paths. The phase shift selection circuits have different respective impedances relative to the communication port and the respective impedances vary for the different frequency bands. Other methods and systems are also disclosed.
