An extremely low-cost frequency source using ADF4350. The frequency range is 140MHz~4.4GHz.
The board thickness is 1.6mm. The size is the same as Raspberry Pi Zero. The 65mm * 30mm
software part comes from github.com/NightIsDark/ADF4350 . Thanks
You can directly JLC the patch, pay attention to
the Type-C port of the NC component to connect to the computer, and write the frequency on the serial port; I may get a host computer
when I have time. Since the goal is low cost + usability, there are a lot of confusing operations in the schematic part, so don’t copy it.
Just take HackRF and measure it as follows. Anyway, it works.
