A dual-band dual-input amplifier transmitter

Example discloses a dual-band dual-input amplifier transmitter of the present invention, the transmitter power amplifier comprising: two-band dual-band input circuit includes at least an input terminal of the input baseband signal after DPD processed output; modulo circuit input the baseband signal is modulo processes and outputs; signal separating circuit receiving a dual-band baseband signal input circuit input and modulo the baseband signal analog value circuit input and decomposition, multiplex the obtained decomposition decomposed signal; modulation circuit receiving the multiplexed decomposing the signal processing and post-processing to give two signals modulated to the respective working frequency output to the dual-band power amplifier. Herein by the above-described circuit structure, the multiple-input single dual-band power amplifier into the scene, when the single-input dual-band power amplifier, the dual-band power amplifier in a dual-input dual-band signal transmitted in parallel with respect to, can significantly improve the dual band transmitter the overall emission efficiency.
