Intermodulation distortion is one of the most interesting signal analyzer measurements. Often abbreviated IMD, it is an important metric of linearity for a wide range of RF and microwave components.

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.

Microwave photonic links (MPLs) combine the expansive bandwidth and low loss of optical fibres with the versatility of radio frequency signals to enable high-speed, long-distance communication and ...
