The present invention belongs to the wireless communication technology field, and especially relates to a configurable low-power full-digital transmitter. The configurable low-power full-digital transmitter mainly comprises a configurable baseband signal processing circuit, a coordinate conversion circuit, a phase predistortion calibration module, a phase modulation module, an oversampling and noise shaping module, an amplitude control logic module, a full-digital dual-power difference power amplifier, a passive matching network, a low-dropout linear voltage stabilizer, a full-digital frequency synthesizer, a serial peripheral interface, an output load and other circuit modules. The transmitter is flexible in circuit and reconfigurable (the transmitter can reconfigure baseband signal bandwidth, radio frequency points and emission power, etc.), and can satisfy application requirements of different wireless communication standard protocols (such as a Bluetooth low energy consumption technology (BLE), a wireless body area network (WBAN) and narrowband internet of things (NB-IoT), 802 and 11ah based on a honeycomb). Besides, the transmitter is simple in structure, is a full-digital circuit, is low in power consumption, high integration and low in cost, and easy to apply in an actual wireless communication system, etc.
