This works for me, an SPF5189 Amplifier followed by a 3dB attenuator & into an Analog Devices EVAL-CN0417-EBZ board.
The EVAL-CN0417-EBZ board has a small fan to keep it cool, & contains a 2.4G bandpass filter.

I just completed a new grounstation with the SGlab amplifier and their upconverter, works like a champ in my opinion, see also: https://pa1ejo.wordpress.com/2…ble-set-up-for-oscar-100/

At 13V I measure around 5.5 Watt CW output.
I do not know how accurate my meter is.
Has anyone tested the sglabs PA at 12/14/16/18/20/22/24/26/28 volt?
Thanks, Henk

Hi Henk,
all the best for 2022, good DX and #staysafe.
Here please find my table of measurements I made with my setup last year.
TX is a Yaesu FT818 driving the SG Labs up converter and than pushing the SG Labs 20W PA.
If you have further questions let us make a skid on QO100 to talk about my results.
The measurements where made by using a Siglent SSA3032X Spektrumanalysator.

You can take it to 28 Volt, I run it at 24 Volt.

PA1EJO, we (PE1GLX and me) liked your 12 to 24v converter, and we just bought this as well. Our transverters are finished, no space left, so we will use it as an outside box.
