    Amplifying AD9850 DDS for 5Watt output. OPamp or RF FIT?

    Absolutely. Faraday cages all around! Don't want to interfere with any Hamsters. Copper mesh shielding (1-2.5mm) around the antenna and a metal box to shield all the other components. Coaxial cable from my matching network to the antenna. (Building a low cost Helicon plasma source)

    Amplifying AD9850 DDS for 5Watt output. OPamp or RF FIT?

    Hello. I am looking to amplify a sinusoidal signal generated from an AD9850 DDS. It appears the output is 1Vpp @ 27.12MHz when connected through a 50ohm cable to an oscilloscope. I need the total power output to be 5watts after amplification with a very clean sinusoid. The output will be...

    Building Your Own RF Plasma Source: Safety Precautions and Project Ideas

    Hello to all. I have experience in building Helicon plasma sources using commercial grade etching equipment. That is, I know what commercially available pieces to connect together in order to produce a plasma, however I would like to understand the inner workings of this equipment and home...
