Step Attenuator Design, Build and Test (073a)

**CORRECTION** That is 2^8 * 3 = 768 tests *NOT* (8!+1) * 3 = 120,963 tests. Either way, still too many tests to perform. **POWER RATING** Do not apply any more than 250 mW to this attenuator (A.C. or D.C.). That means no more than 3.5 VDC or 250 mW R.F. or any combination of A.C. and D.C. that amounts to 250 mW. ----------------------------------------------------------- In this video I will walk through the Design Build Testing of an eight position Step Attenuator. I will compare its performance to it predecessor, another eight bank Step Attenuator made a LONG time ago with leaded resistors. You will find a LINK to the ZIP file below which contains: The Formulas and Values Sheet which also includes a DigiKey shopping list All of the needed design files All of the test results for both the Old and New versions You will also find LINKS to the OSH Park Projects for both the Single Bank prototype and the Eight bank complete Step Attenuator. NOTE: I am still experimenting with this new mic and it sounds like I have some over-driving on the audio. I'm still trying to track down the source.
