Abstract
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.
