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.
