I tested the EVB and find out the divide by 2 output power changes over the
frequency range, especially the ADF4360-2 EVB.


I think the power test result is reasonable, because the EVB output are narrow
band matching, it only optimized for direct output, if div/2 output they will
get much less power. they need to change output matching circuit to get higher
div/2 output. or they could change the RF choke inductor to 50 ohm resistor to
achieve wide band matching, and get similar output power of direct output and
div/2 output. But in this case output power is not optimized to max power.
