Dear Analog,


I am searching for a frequency synthesizer with following features:

1. Fractional-N type

2. Integrated VCO (optional)

3. Frequency range to be generated : 1GHz to 5 GHz (approximately).

4. RF output "Phase sweep" option is must (e.g ADF4351, register1,or ADF4355-3 register03)

5. Waveform generation option is also required (like in ADF4158)

6. Phase noise should be better than -100 dBc/Hz (10KHz offset).


We are already using ADF4158 frequency synthesizer. For one of our new project, we need to sweep the phase of the RF output . Also we need better phase noise performance than existing ADF4158 based system.


Secondly, Kindly give the VCO phase noise performance of the ADF4355-2 at 10KHz offset.
