This comprehensive guide explores four critical parameters of RF amplifiers - gain, noise figure, linearity, and efficiency. Understanding these specifications is crucial for engineers designing high-performance amplifiers that deliver clear signal transmission while balancing power consumption and signal integrity in modern communication systems.

Standards and requirements for hardware testing must be carefully tailored rather than rigidly applied. A thorough understanding of source documents, appendices, parent standards, and similar projects helps ensure testing is efficient and relevant for specific hardware applications, preventing delays and oversights.

Explore the hidden complexities of measurement uncertainty in EMC testing, where precision meets practicality. Learn how subtle variations in measurements can impact product compliance, engineering decisions, and ultimately, market success.

Learn to set up in-house conducted emissions testing for line-operated products using basic equipment like spectrum analyzers and LISNs. This practical guide helps engineers perform pre-compliance EMC testing right on their benchtop, potentially saving time and money.

Discover the key sources of uncertainty in radiated emissions testing and learn how to calculate measurement uncertainty budgets. Essential insights for EMC professionals seeking more accurate and reliable test results.

Discover essential but often overlooked aspects of compliance engineering, from material selection to ethical conduct. Learn practical insights for navigating regulatory landscapes while maintaining product safety and integrity.

A revealing EMI analysis of the popular BeagleBone Black processor board uncovers concerning radiation levels and design flaws, suggesting potential challenges for industrial applications. The detailed investigation includes near-field scans, cable current measurements, and PCB design review.

Reverberation chamber testing offers major EMC advantages over traditional methods by exposing units to electromagnetic fields from multiple angles simultaneously. This approach saves time, better simulates real-world conditions, and catches vulnerabilities earlier in development.

This month's Practical Engineering explains how to use the Welch-Satterthwaite formula to calculate the effective degrees of freedom and expanded uncertainty in a measurement uncertainty analysis. It provides a practical example to demonstrate the application of this formula.

This month's EMC Bench Notes reviews three affordable pre-compliance measurement software options that can simplify and automate the process of conducting in-house radiated emissions testing, saving time and costs compared to manual methods.
