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 ...

In [Dave’s] latest episode of the EEVblog he takes a look at constant current dummy loads. These are used to test power supply designs and instead of just chaining resistive loads together every time ...

As part of a power electronics design project involving a 3.6-V dc-dc converter, it became necessary to test and accurately characterize the planar transformer shown in Fig. 1. Transformer operating ...

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 ...
