Must have missed that previous post.
As stated, everything is in the datasheet.
As far as an XLS file just make your own from the calculations in the datasheet.
There is no "current circuit" It's a module to buy from China or wherever you buy modules in your local area.
As far as the frequency being that low, I don't know if it will operate there.
The project is on hold due to the availability of RF signal generator(s) that I ordered capable of harmonic generation, arrived after 3+ months delay from my post above.
It will be picked back up after the backlog of other projects have been completed.
