Abstract
Front-end architecture having switchable duplexer. In some embodiments, a front-end architecture can include a first receive signal path having a first receive filter coupled to a first antenna, a second receive signal path having a second receive filter coupled to a second antenna, and a transmit signal path having a transmit filter. The front-end architecture can further include a signal routing assembly configured to couple the transmit filter to the first antenna in a first mode, and to couple the transmit filter to the second antenna in a second mode.
