Hi,
ADISIMPLL model for ADF4401A is being developed at this moment.
Allowed LO input power is specified as -3dBm to +3dBm and LO power at higher end will provide slightly better phase noise at the output.
Performance of the LO signal (regarding the phase…
Hi Support
On the Analog Devices product page for the ADF4401 a video is available presented by Kazim Peker entitled ‘Perfection of Translation Loop: Eliminating Spurious Signals’. On slide 17 an ‘integrated doubler for 8 & 8.8GHz’ is mentioned…
The ADF4401A translation loop has the best phase noise performance, as the 20logN phase noise added by the N divider is avoided, but it requires high quality LO and PFD frequency source(s), as the phase noise of the LO & PFD signals will affect the overall…
Our lowest phase noise production released PLL+VCO is the ADF4401A which provided DRO type phase noise performance but implemented with a PLL+VCO translation loop architecture by using the SMA100B for the Offset LO. The ADF4401A offers <10fs RMS wideband…
Hi Mike,
I can't send any modified PLL models as these will only work on our custom in-house/debug version of ADIsimPLL for internal use only - the PLL models are fixed otherwise.
We weren't able to get this fix into the ADisimPLL v5.4 release, but…
Great question..it really depends on your application but if we had to choose one device to single out on the vector of performance above all else then it’s the ADF4401A Translation Loop IC. It’s a novel architecture that is used in INST applications…

I am curious about how phase noise is transmitted and superimposed inside a phase-locked loop. Is there any great Technical Articles published by ADI or a book or paper written by someone else that you may recommend to me which describes the principle of…
