@dylanmc - Dylan,
And check this posting I did awhile back, too ------> LimeSDR as a Amateur Radio Transciever
That’s the amplifier I’m going to use with my LimeSDR and the only thing you’d need is a 10dB pad because the amplifier drives at 0dBm, but outputs 45W (+46.53 dBm).
Let us know if you need anything else…
