Mira OK1UFC described two possibilities of how to use cheap small power amplifiers for boosting signal on 2.4GHz. If you love QRP and don’t mind the reports you receive for weaker, but sufficient signals on the QO-100 satellite for communication, you have several options for which PA to get.

Very interesting article from M1GEO about how to make a 2.4GHz transmitter using a Lime SDR and WiFi amplifier. In last time WiFi amplifiers are a very popular choice for cheap and usable source to amplify the signal on 2.4GHz or 5.7GHz. Especially are popular for use in setups for communication on Es’Hail-2 (QO-100) satellite. On the internet, you can…

Daniel Estévez EA4GPZ/M0HXM (more info https://destevez.net/about/) has built ground station based on LimeSDR Mini. The signal from SDR is amplified first with GALI-84 driver amplifier and then with a purposed 100W amplifier for UMTS . For downlink Daniel uses LNB. Full description of these project with much useful information you can find on: https://www.crowdsupply.com/lime-micro/limesdr-mini/updates/field-report-limesdr-mini-satellite-ground-station Support Daniel’s work: https://destevez.net/donate/ All photos: https://www.crowdsupply.com/lime-micro/limesdr-mini/updates/field-report-limesdr-mini-satellite-ground-station
