Hello, I used HMC698+HMC733+OPA184 in the design, PFD is a 100MHz sine wave, SSB is -155dbc/Hz@1KHz, the final output frequency is 10GHz, and the phase noise is -101dbc/Hz@1KHz. I have used more An LDO, I don’t know why SSB is not so good. I am concerned that the phase noise of 13GHz output on page 6-12 of HMC698 datasheet is -108dbc/Hz@1KHz. Can you provide the detailed design of circuit on page 6-12 of HMC698 datasheet? Parameters, including schematics, is the reference signal a sine wave or a square wave?
