QI would like to use a single chip balun for the output of the ADF4360. However
there doesn't seem to be any output impedance information in the datasheet.
Only an application circuit using lumped elements. I was wondering if you could
advise on what impedance ratio I should use for a balun i.e. 1:1, 2:1, or 4:1?
AI have attached a document that looks at what matching network to use in order
to get maximum power o/p from the ADF4360-1, the same principle can be applied
for the lower frequency versions.
