One of the major challenges in communications system design is to successfully capture signals with adequate fidelity. In order to avoid the effects of blockers, signal distortion, and sensitivity ...

What are S-parameters? The multiple types of S-parameters beyond the small-signal variety. Using S-parameters, we can represent even the most complex RF device as a simple N-port network. Figure 1 ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

If you’ve ever used an RF signal analyzer, you’re probably used to seeing displays like the spectrum graph or constellation plot. Of course, trusting the answers you get from the instrument often ...

Most of us know that to get the best possible WiFi signal, you want there to be as few walls as possible between you and the Access Point. But that might soon change, as researchers at MIT have found ...
