Hi
The simple approach is to buffer it with a few ‘125 buffers in parallel. Then convert
to sine wave with a T-network matching section. There are a lot of matching calculators
on the web. Something in the 50 to 200 ohm input range and 50 ohm output is a reasonable
way to go. More gates and higher power = more output. Lower input impedance = more output.
