An Rf Sampler Samples The Transmitted Rf For Testing.

This sampler has two outputs, one an attenuated and the other a diod. The same radio design example above can be implemented using an rf sampling adc. This buffer allows you to connect your counter to any rf source from 20 mw to 200 watts, from 200 khz to 60.

Following The Design Notes In This Article From W5Qn, I Got Started.

I did not have the correct capacitor so i used 2.01 mfd caps in parallel for the.02 value. As you may have guessed, due to the case geometry the output attenuation will depend on the signal's frequency. Easy project and works very well!
