ADF4355 - Optimum o/p power

According to the datasheet, see extract from the datasheet attached, there is a way to obtain maximum power from the device by using a pull up inductor.

 

The problem we have got is that the synthesiser will be used to produce frequencies from 687 – 6000MHz, as you see, a huge range.

 

What kind of output network (resistive or reactive) would be optimum to yield a good power level across this frequency range?

 

Of course, as the frequency goes up we would expect some degradation in
the power level.

We just need to know if there is an optimum combination of C
and L recommended for this wide frequency spectrum.
