Well,
You may recall back here when I became very inspired by a project by GM8BJF using some eBay sourced Chinese modules to create an ADF4351 based signal generator.
There's another variation on that theme that has been published in the May 2019 Scatterpoint. Scatterpoint is the journal of the UK Microwave group, membership is about 3 bob and a conker so you have no excuses for not joining.
This time it uses an ADF5355 to generate signals from 52MHz all the way up to 13.6GHz.
The 4.4GHz generator has proved extremely useful, this one is a must.
I've modified the design and the software a little so that the 100MHz clock is generated by am ADF4351, rather than an OCXO as per Brian's design.
Brian has made the software available here, and my modified version is here. The AD4351 is a version of the evaluation board from SV1AFN - and it gets its reference from my 10MHz shack frequency reference.
The software runs on a SAMD21 ARM Cortex M0 which runs at a 48 MHz clock rate. This is supported by the Arduino IDE but is not something I had used before.
Its still WIP, but the project is up and running OK.
How cool is this?
Here's Miss Maggie Cat and Miss Pepper Cat doing what they do best:
