Outphase power amplification transmitter based on phase controllers

The invention relates to an outphase power amplification transmitter based on phase controllers. The transmitter comprises a complex signal controller, a local oscillation generator, digital to analog converters, two analog RF devices and the two phase controllers, wherein the local oscillation generator generates original local carrier waves; the digital to analog converters are connected with the complex signal controller, and convert baseband signals into analog signals; each analog RF device is connected with one digital to analog converter and the local oscillation generator, and modulates analog signals to the local carrier waves; both the phase controllers are connected with the local oscillation generator, and adjust the original local waves to two outphase local carrier waves; and the output ends of the analog RF devices are connected to each other, the first input ends of the analog RF devices are connected to the analog to digital converters respectively, the second input ends of the analog RF devices are connected to the phase controllers respectively, and thus, the analog signals are modulated to two local carrier waves respectively. Compared with the prior art, the development difficulty is reduced, and the link cost is reduced.
