Patent abstract
A low cost, low phase noise microwave synthesizer includes a DDS modulation circuit and a phase-locked loop. The DDS modulation circuit modulates the output of a DDS to a high frequency. The phase-locked loop downconverts the DDS output and locks the downconverted signal to a relatively low frequency, fixed reference.
