We usually reserve the honor of Fail of the Week for one of us – someone laboring at the bench who just couldn’t get it together, or perhaps someone who came perilously close to winning a Darwin Award ...

These days, we are spoiled for choice with regard to SDRs for RF analysis, but sometimes we’re more interested in the source of RF than the contents of the transmission. For this role, [Drew] created ...

An RF transmitter is a device that creates a radio signal containing information that with the use of an antenna propagates some distance. The earliest practical RF transmitter was known as a spark ...

RF mixers convert RF power at one frequency into power at another frequency to make signal processing easier and more efficient. The frequency that is to be shifted is applied at the RF input and the ...

Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

Today’s RF test instruments are highly complex products and are therefore characterized by a wide variety of specifications. We have presented a three-part series on a wide array of RF instrument ...

RF signal observation has evolved from yesteryear’s spectrum analyzer to today’s RF recorder. Swept spectrum analyzers, FFT analyzers, and real-time signal analyzers all had limitations. Today’s RF ...

Radio frequency small-signal amplifiers (as opposed to power amplifiers) find many uses around the radio shop as well as in the field. Sometimes, a higher signal level is needed to operate a test ...

Engineers have built a 3 W hybrid system that sends power across a sealed rotating gap via magnetic resonant coupling while ...
