loop bw to locktime
Mainstream newly designed PLL chips have linear phase noise performance of PFD. It's clear that in single loop, Fout=N*Fpfd.
In @nanlog Device's phase noise floor calculation, like ADF4107, phase noise in loop BW:
L(fm)=Inband phase noise floor(mainly depending on PFD...
In my opinion, use PLL would be much better: smaller size, better out-band phase noise than Mr.sinatra's method. With a well designed PLL, there are less spur than frequency multiplication. At 4GHz, the componets are easily be found like Analog Device ADF4113 PLL chip and Hittite VCOs. Try it...
Why not try E@glew@re? it's a complete and fast and easy to use RF beginners and professionals.
You can prove and fast your designs much better than @DS and others. I think the suites' circuits fuction and filter fuction is No.1 in simulation.
I changed my soft from @DS to E@glew@re the first...
Use them in your way
I used them all. Gene$y$ is accurate and cheap, easy to use. AD$ is powerful but difficult for beginners. MWO is between the other two.
Gene$y$ and AD$ in very accurate in microstrip circuits. All of them are suitable for lumped circuits. In system level, AD$ is...
