    摘要： 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.

    摘要： A printed circuit board includes a signal trace, capable of transmitting signal, and a pad. The pad is electronically connected to the signal trace. The pad is placed on an external surface of the printed circuit board. The pad includes a body and an extending portion extending from the body. The body is configured to weld an electronic element. The extending portion defines a first edge and a second edge parallel to the first edge. The length of the first edge is greater than that of the second edge. The extending portion is connected to the body at the first edge, and the extending portion is connected to the signal trace at the second edge.
