Design on a Wide-band Frequency Synthesizer Based on Harmonic Frequency Mixing Technology
Zhang Da-he · Radio and communications technology · 2013
Based on elicitation of frequency mixer,combining accomplishments of some relevant documents,a wide-band frequency synthesizing manner using frequency mixing is proposed.Based on clear analyses on the principle of harmonic frequency mixing and practical combination harmonic mixing and frequency synthesis,an implementation scheme of wide-band fine-resolution frequency synthesizer with low phase noise is given.Phase noise and spur rejection specifications of the scheme are calculated.An experiment results show that the frequency synthesizer based on harmonic mixing technology has excellent phase noise and spur rejection performances,and can provide some reference for design on wideband frequency synthesizer with low phase noise.
