10MHz square to sine conversion

Hi,

I need to convert 10MHz Square wave to sine to drive an ultrasonic transduser. I have read a lot of suggestion. But the frequency that I will work qualifies my study.

I have researched 8th order low pass filter IC's. But their frequency is too low for my study.

Are there anybody has a new idea???

if you have a 10MHz transducer, don't worry about it. I use those and do not even give it resonant frequency. You are actually better off not resonating it since it will likely get out of control unless you are running closed loop.

What are you trying to do?

I hope you're not assuming that ultrasound at this frequency will travel through the air because it won't.
