FREQUENCY AGILE MULTIBAND TRANSMITTER USING A RADIO FREQUENCY DIGITAL TO ANALOG CONVERTER |
摘要 |
Embodiments of the claimed subject matter provide a method and apparatus for generating a first radio frequency digital signal and providing the first radio frequency digital signal to a radio frequency digital-to-analog converter operating at a sampling frequency. The output of the radio frequency digital-to-analog converter includes a first carrier signal corresponding to the first radio frequency digital signal and having a first frequency below the sampling frequency and an image of the first carrier signal having a second frequency above the sampling frequency. The output of the radio frequency digital-to-analog converter is filtered to select the image of the first carrier signal for transmission. |
