RF DIVIDER USING DIRECT DIGITAL SYNTHESIS |
摘要 |
An RF divider directly synthesizes a desired RF as a digital pattern that can be programmed and output at a VCO frequency. An exemplary RF divider comprises a pre-sequencer and a parallel-to-serial converter. The pre-sequencer successively outputs consecutive M-bit sections of a parallel word, where the parallel word comprises one or more copies of a frequency dividing bit pattern defining a frequency divisor. The parallel-to-serial converter performs a parallel-to-serial conversion on the M-bit sections of the parallel word based on the fixed radio frequency to generate an output signal having the desired radio frequency, where the output signal comprises a serial bit stream of the parallel word. |
