Power Amplifier for SDR VHF / UHF [Semi-OffTopic]

Hi to all!! first of all sorry for my basic English.

i want to know if someone has a circuit for power amplifier for SDR, particularly in VHF (146 MHz) and UHF (436 MHZ), to recommend. In this stage i want to make two different amplifiers.

I’m acctually made some test with LimeSDR Mini and HackRF (it has 10mW of power output) but to work with satellites i want almost 5W.

I know its not 100% related to satnogs (because the station has only RX) but maybe can use it in future.
