Amplifier Classification A vs. AB
Amplifiers are designed in many ways. One distinction is how the amplification devices are biased. They can be biased in different ways that affect performance and efficiency. This is called the Class of operation. Class A, B, or AB are commonly used and referred to in specifications for high power RF & Microwave amplifiers. This paper discusses the differences between the different classifications and what it means with respect to performance.
An understanding of Wi-Fi 6 certification, as well as regulation of the 6 GHz band, is critical for companies seeking to capitalize on next-gen Wi-Fi.
This article describes the modeling of a SATCOM link, specifically the use case of using a satellite overlay to extend service continuity to IoT devices in a poorly covered rural area.
