    摘要: An antenna duplexer is provided, which can be built with a smaller size and lower height than ever without compromising out-of-band attenuation characteristic and isolation characteristic between a transmit terminal and a receive terminal. The antenna duplexer includes a transmit filter provided between an antenna terminal and the transmit terminal, and a receive filter provided between the antenna terminal and the receive terminal. The filters are enclosed by a package, in which a ground pattern for the receive filter is separated from other ground patterns.
