A configurable wireless transmitter comprises a digital baseband circuit, a digital-to-analogue conversion circuit, an analogue baseband circuit, a radio frequency front end circuit, a frequency synthesizer, a band-gap reference source circuit, a serial control interface circuit and a parallel data interface circuit. The radio frequency front end circuit comprises a powerpreliminary amplifier, a power amplifier and a feed through buffer. The power preliminary amplifier is used in broadband cluster application, and input signals are converted to radio frequency signals with frequency and bandwidth required by the broadband cluster application. The power amplifier is used in narrow-band private network application, and input signals are converted to radio frequency signals with frequency and bandwidth required by the narrow-band private network application. The configurable wireless transmitter is low in power loss and high in integration level. The radio-frequency signal center frequency output by the configurable wireless transmitter is from 100MHz to 5GHz, bandwidth supports frequency from 5kHz to 20kHz, flexible configurable performance is achieved, and the requirements for different communication standards can be met.
