Hello,

What are the specifications for "powerfull" and "frequency"?

Bertus

Anyway, I call this NOT high frequency.
In my opinion anything above 1 MHz is high frequency.

many thanks of all.it works
now output vp-p is 12v
and
if i want to give boost to my frequency
now how i can???
There's a frequency doubler trick you can do with some XOR gates - cascade as many as needed for multiples of 2.

A bit more complex is the PLL - You use a phase comparator to compare Fin with that of a VCO - The VCO is controlled by an error voltage via a LPF from the phase comparator.

In its raw form it locks the VCO to Fin, but if you pass the VCO through a digital divider before feeding it back to the phase comparator - then the VCO has to run at <divide ratio> times Fin to keep up.

Hello,

If you only want to amplify the signal, you could use an 7406 TTL chip.
That has an open collector output wich can be pulled up to 30 Volts and can sink 30 mA.
