A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.

With the roll out of new digital wireless systems, the measurement of medium power RF signals, typically from transmitters and particularly in the field, has become more prevalent. In response, a host ...

Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...

One very successful trick I use to simulate radiated immunity on the bench is to run an RF generator into an H-field (loop) probe. The best level seems to be +15 to +20 dBm. This will generate an ...

Measuring RF power at high frequencies is tricky. What if one sensor could cover it all, cut test time, and simplify complex ...

To address the stringent requirements of the latest microwave and mmWave testing, Siglent has increased the addressable frequency range of its RF signal generators to 40GHz. The SSG6000A has a wide ...

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

As dependence on wireless devices that emit RF radiation continues to grow, so do the complexities of those devices and their international regulatory requirements. Specific absorption rate (SAR) ...

This article discusses the GALANT adaptively steered antenna array and receiver and demonstrates the test scenarios generated with the GNSS simulator. Exemplary results of different static and dynamic ...

Recently, a reader wrote to me seeking a copy of a paper on measuring the transient peak-to-average power ratio of DTV signals. So perhaps the topic of DTV signal power, which is so different from ...
