Mesuro announced the introduction of its MB Series active load-pull systems at IMS 2009. The MB Series enables device and power-amplifier manufacturers to characterize their devices within an ...

云圈 | 进“云脑智库微信群”,请加微信:15881101905,备注您的研究方向 说到射频PA（Power Amplifier，功率放大器）的设计和应用，有两个名词经常被大家提及：Load-line与Load-pull。在使用中，这两个名词太过常用了，以至于对这两个名词后面的理论依据反而讨论不多。

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 ...

In general terms, power amplifiers (PAs) used in communications systems must be large enough to amplify envelope peaks. This leads to amplifiers designed to offer the best efficiency at peak power ...

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 column is the first in a series of columns dedicated to one of my favorite subjects: troubleshooting. I'm a systems administrator during the day, and although I enjoy many aspects of my job, it's ...
