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, ...

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.

The prime consumer of power in a wireless device is its RF power amplifier (PA), so assessing PA performance is critical. To maximize efficiency, the PA must operate as close as possible to its ...
