Abstract: A radio-frequency architecture is provided. By setting an independent radio-frequency channel including a B13 duplexer, LTE_B13 main wave signals, being output by a power amplifier and passing through the B13 duplex, are emitted directly from a second main antenna without passing through any non-linear device.
