Adf Pll Controller
A simple way to generate signals from 35MHz to 13.6GHz is to buy a module from China. They are available in different PLL versions and boxes.
Ex.
- ADF-4351 (35MHz => 4.4GHz)
- ADF-4355 (54MHz => 6.8GHz)
- ADF-5355 (54MHz => 13.6GHz)
These modules can be operated with buttons or touch screens. This works when just a signal needs to be set and used. What I know is the ADF-4351 version the only one that allows to set the power. I made a simple software that can set the frequency, power and a simple scan/sweep function. The sweep is only 10Hz, so it is more a slow scan.
You can download the program here:
Below a 5355 version and to the right a 4351.
Other versions are available, however they do not have the options to use the serial port for communication.
With a module as below I made a simple SA range extender.
