While it might seem counterintuitive on the surface, there are a number of cases where dumping a large amount of energy into a resistor simply to turn it into heat is necessary to the operation of a ...

I sold low-power FM transmitters in a former job, and one of the things I learned is that most customers lacked a suitable dummy load for testing. In new LPFM or translator applications, you can save ...

More than 175 miles above Earth on Monday, nitrogen gas inflated an antenna the size of a tennis court. NASA hopes the experiment also has expanded options for cheaply putting bulky equipment into ...

This dummy-load circuit, which is useful for testing power supplies and power amplifiers, is based on the Maxim MAX6006 voltage-reference IC and MAX480 operational amplifier. This dummy-load circuit ...

Like most engineers, I have used dummy loads spanning DC through RF, and from a few watts to hundreds of watts. Most of these loads were built up from basic resistors, and in some cases special ...
