Hi Jayson. Ive been playing with the black ADF4351 PLL boards available on the web. At the beginning I thought it was going to be way to hard, it isn't but there are somethings that need doing to these boards to make them work properly.
These things.

The PLL board needs something to drive it on and this you can do with an Arduino. Im using a very small and cheap "Pro micro"
https://www.aliexpress.com/item/32768308...04875532_4
Arduino micros are very easy to programme and all the development tools are free and easy to use. You will need the IDE to load code into the Arduino which is downloaded from here.
https://www.arduino.cc/en/software
So with all the above three things on hand all you need is some code and thats here.
https://github.com/F1CJN/ARDUINO-ADF4351...090319.ino
Even if you don't do any of the mods to the PLL board it will work with the above code and give you strong harmonics at 10Ghz.
The connections to the PLL board from the Arduino are listed in the comments in the code, theres only 4 of them. The Arduino board connects to your computer via USB so all you need to do then is copy the code into the IDE and upload it to the Arduino Pro Micro. In the code above all you need to do is change the number at line 80 to change the output frequency but remember these PLL's only go to 4.4Ghz so for 10Ghz pick 10ghz/3.
If you want anymore help just drop me a message....or if your not brave enough to give this a go
I may be able to help with a pre programmed Arduino board and maybe a PLL board but Im a bit short of those at present.
Now before anyone comments...this is not a perfect solution I know that but it works.
And the black boards are cheaper than a one of ADF4351.
