ADF5901 VCO fundamental frequency

Please tell me if the ADF5901 uses a fundamental 24GHz oscillator.

I think HMC739 is a 12GHz core that is doubled, is ADF5901 similar?

Thank you

  • Apologies for the delay in response.  I'll get the responsible engineer to respond.

    After looking at the datasheet, the divided down AUX/AUXB output frequency range would imply the core is 24 GHz.  See the "AUX PIN OUTPUT" section in the Specifications Table. 

    24GHz / 2 = 12 GHz & 24 GHz / 4 = 6 GHz

    Also, the first page of the datasheet indicates a 24 GHz core.
