ULTRA-FAST HOPPING FREQUENCY SYNTHESIZER FOR MULTI-BAND TRANSMISSION STANDARDS

摘要

A system, device, computer program product, and method provide fast frequency hopping. The system includes a terminal and a base station in communication with the terminal to receive an output signal. The terminal includes a communication interface, a processor, and a frequency synthesizer. The processor couples to the communication interface and selects the transmission center frequency of the output signal from a plurality of center frequencies capable of transmission from the communication interface. The frequency synthesizer includes a frequency controller, a multi-band oscillator, and a frequency calibrator. The frequency controller controls a center frequency for the plurality of center frequencies and selects the center frequency corresponding to the selected transmission center frequency. The multi-band oscillator generates a local oscillator signal having the selected center frequency. The frequency calibrator defines a correction value for the center frequency of the local oscillator signal and sends the correction value to the frequency controller.
