| 摘要 |
Front end circuitry includes at least three antenna nodes, a first duplexer, a second duplexer, a first diplexer, transceiver circuitry, and front end switching circuitry. The transceiver circuitry is coupled to the first duplexer, the second duplexer, and the first diplexer. The front end switching circuitry is coupled between the antenna nodes, the first duplexer, the second duplexer, and the first diplexer and configured to selectively couple the first duplexer to a first one of the antenna nodes, selectively couple the second duplexer to a second one of the antenna nodes, and selectively couple the first diplexer to a third one of the antenna nodes. |
