The MiniKits EME162-1200 1W amplifier will do it (the specs that come with it actually specify 800mW out at 1dB compression) but you may have to select different attenuator resistor values to match the Commtech. They quote 18mW drive for 800mW output with no attenuator. It comes with components for an optional 5dB attenuator (on board). Does what it says it does. Takes 280mA. Needs a small 20mm square heatsink. If you ever go digital don't expect much more than 60mW to 100mW output with good linearity. Digital is very unforgiving.
