In this first part of a two-part article, we’ll discuss the use of radio modules to enable wireless connectivity of electronic and consumer products, and how to approach radio, EMC and safety regulatory approvals in North America for radio modules and equipment which contain radio modules.

The goal of this paper is to investigate fundamental mathematical and statistical algorithms for the spatiospectral analysis of electromagnetic coupling in large, complex electronic systems. A novel stochastic Green’s function and a statistical representation formula are proposed, which statistically replicates the multipath wave-chaotic dynamics inside cavity environments. The work achieves a physics-based modeling and simulation capability that predicts the probabilistic behavior of high power radio-frequency induced current and voltages in complex electronic systems.

Ever tried to measure low-level signals in the presence of noise? Or wanted to capture a measurement isolated from ground, like that of an ungrounded hand-held digital multi-meter, but also needed to capture finer details of the signal, like those captured with an oscilloscope?

Is your test software the goose that has laid its golden eggs or is your software misbehaving? Does it run amok? The purpose of this article is to provide an understanding of the software validation requirements, the validation rationale, and suggest independent tools that will allow you to develop your own test software validation process.

More power costs more money when it comes to broadband power amplifiers, so we typically only specify/buy to meet our current needs rather than what we may need in the future.
