Gday all,
I have added detailed (but incomplete (draft)) documentation to my 432MHz transverter web page.
Sorry about documentation taking so long (it's not my favorite activity :( )

Before I get jumped on :)

I have picked up a mistake with the conversion gain!
should be around 11db. and I am in the process of editing it!

There are other devices that I have been using as well and this is where the mistake originated.
Other MMICs tried are;
INA02184 – 31db of gain (21db of transverter conversion gain), 2db Noise figure, 23dbm IP3
SGA4586 – 26db of gain (16db of transverter conversion gain), 1.7db Noise figure, 27.7dbm IP3

The SGA4586 devices are out of stock. (I am currently not able to supply)
