Base on Analog Devices ADF4351 PLL generator IC it is good substitute for much more expensive development board. You will need to program it over I2C bus from some 3.3V development board thou. There is plenty of Arduino UNO projects, but I suggest use of Arduino DUE or some other 3.3V-Ready boards.

I control this module via Arduino nano,sketch from http://f6kbf.free.fr. It works fine, I check it from 50 MHz to 2.4 GHz with no problems. Good choice!

Great thing, I ordered another one to also make a RF generator for a friend. In the first case, the internal reference deviated a little, but in the latter case it did not. Since the temperature stability of the oscillator is satisfactory, there is a simple solution. The oscillator frequency is measured and this value is entered into the SW. The CE pin must be HIGH for proper operation. We can connect it to 3.3V, but it is better to select a free pin on the processor, set it to HIGH and connect it to CE. I use ESP32 myself and I connected the CE pin to EN on the processor. For low phase noise, the power supply to the ADF4351 module must be separate from the processor power supply.

работает все отлично. гармоник сигнала много правда. для работы в радиоэфире нужны будут фильтры.

A good PLL synth. The ADF4351 from Analog Device is a PLL synthetizer capable of generating frequency from 35 MHz to 4.4GHz with very low jitter. A useful toy for a radio amateur.

This one with ADF4351 is abit better than similar a bit cheaper product with ADF4350.

Lässt sich leicht mit einem Arduino ansteuern. Dabei unbedingt beachten, dass die Eingänge nur 3.3V vertragen! Also für Data, Clk und LE dreimal je einen Spannungsteiler aus einem 1.8k und einem 3.3k Widerstand zwischen schalten. Muxout ist ein Ausgang und kann direkt verbunden werden. Außerdem muss CE mit 3.3V verbunden werden, sonst reagiert das Modul nicht!
