Do I need active Loop filter in order lo lock 4GHz ? I didn't see any data regarding the Vtune values Vs Fout
The ADF5355 uses a passive loop filter along with a charge pump supply voltage of 5V.
The applications circuit in the Rev B datasheet (which currently incorrectly shows Vp = 3.3V instead of 5V) is the primary clue.
