ADF4355-2 output synchronization

Hi All,

We want to use ADF4355-2 to generate LO for Demodulator and modulator at the same time.

System RF output frequency maybe will at 3GHz to 4GHz.

We have some question as below need your help!

  1. Does ADF4355-2 use RF outputA and B at the same time?
  2. What is the output power of RFout_A and RFout_B at 3.8G?
  3. What is the delay between RFout_A and RFout_B of ADF4355-2?
  4. Does ADF4355-2 need add a phase adjustment externally to adjust both output port by the same time? Do you have any recommended the parts?

    1. Does ADF4355-2 use RF outputA and B at the same time?  yes
    2. What is the output power of RFout_A and RFout_B at 3.8G? see fig 13 ..approx 5dBm
    3. What is the delay between RFout_A and RFout_B of ADF4355-2? not specified, i would expect the phase to be almost negligible as  any phase difference will be as a result of any phase difference  between the RF o/p stages 
    4. Does ADF4355-2 need add a phase adjustment externally to adjust both output port by the same time? Do you have any recommended the parts? the phase adjust will be applied to the output prior to the o/p stage, this feature is for use to adjust the phase between 2 x ADF4355- devices
