If you work on RF circuits–even if you aren’t a ham radio operator–you ought to have a dummy load. A dummy load is a non-radiative “antenna” with known impedance that you can use to test your RF ...

The sound produced by any given electric guitar is shaped not just by the instrument itself but by the amplifiers chosen to make that sound audible. Plenty of musicians swear by the warm sound of ...

Testing bench power supplies would require the use of a current build and the best way to have one is to build yourself one. The article shows how a custom dummy load is built. Testing bench power ...

This project is made out of few junkbox parts and builds a useful constant current load for switch mode power supply, battery testing, and other applications. A dummy load is traditionally a big ...

Figured this was the best place to put it.<BR><BR>I'm making 50 ohm RF dummy load with resistors. So I'm using 0.5W metal film resistors in parallel, a fair few of them.<BR><BR>I have 49.9 ohms ...
