01.10.23 -- What Really Matters? ESD Specifications For Smartphone Antenna Tuners

Multi-tone testing was initially implemented to increase the speed of immunity testing, but it also improves equipment efficiency, offers higher flexibility, and is fully compliant to standards. Multi-tones are used in measuring modern audio levels in audio devices, broadband devices, and in internet audio.

High-quality, reliable electronic components are a necessity for space applications. After all, when launching mission-critical equipment and people into space, there is absolutely no room for failure. 

In integrated circuits, signal integrity is greatly affected by electromagnetic interference (EMI) and crosstalk. The crosstalk in ICs is a type of electromagnetic interference between two signals propagating adjacently.

With the digital modulation methods and pulsed modes used in modern communications, the demand for accurate, reliable, and efficient RF power measurements continues to grow for next-generation systems.

Antenna gain is a performance indicator gauged in comparison to a reference source. This article explains antenna gain and dispels some of the misconceptions surrounding this valuable metric.

Most measurement errors are the result of a poor setup, from using the incorrect detector type for the signal of interest to failing to make allowances for gating and various forms of modulation.

AC-DC conversion stage in front of any electronic equipment is needed. For this purpose, different solutions exist to convert the higher AC voltage to a lower and safe DC voltage.

Antenna tuners in smartphones, like other electronic components, must be able to withstand electrostatic discharge (ESD) at every stage, from device manufacturing and smartphone assembly to consumer use. This article aims to clear up any confusion about the level of ESD protection required at each stage.
