Load pull characterization is an essential tool to increase the efficiency of power amplifiers. Due to time and cost, vendors have historically performed load pull during design. Today, however, the ...

One way to synthesize it is with an active load-pull measurement system, both in terms of impedance caused by device interaction and the natural impedance caused by the passive structure. The waveform ...

In load pull calculations, power amplifiers are going to need harmonic load pull analysis and load pull contours with wideband electromagnetic tuners. Working with RFIC power amplifiers is difficult ...

This month’s featured RF and microwave products range from amplifiers and signal sources to a very flexible active load pull system. With the existing large choice of amplifiers, there must be ...

RF and microwave devices need to operate as part of a system. Because they are typically not 50-Ω devices, they need to be matched to the rest of the system. That requires characterization of ...
