Amplifying the Sine wave generator.

Amplifying the Sin wave generator.

I have been experimenting with capacitors and inductors and my Sine wave generator.

Building small series and parallel resonant circuits, looking at filters etc.

Decided to try to boost the power output a little from my tiny DDS sine wave generator.

Because its voltage at the moment is under a volt, it struggles to makes its way through the inductors and capacitors which load it up too much.

I looked around for a simple RF amplifier stage to give it a go.

I found this after a search of google images.


Thanks N3ZI, great page of stuff @



Drew it out for a bit of stripboard..

Then i built it up…

Then i tested it…

If you look at the waveforms you’ll notice there is a fair bit of distortion..

 If you look at the scales you’ll see it’s around a 10 times gain in voltage.
