  • Mass Connectivity In The 5G Era

    The fifth generation of mobile networks (5G) is about to enable a fully connected world. With the dramatic increase in data rates and number of connected devices, users will soon be able to enjoy expanded communication between devices and no longer be limited to user-to-user and user-to-device communication. By 2025 an enormous 25 billion devices are expected to be connected under 5G.1. Download the full white paper for more information.

Characterizing Active Phased Array Antennas

Designing and implementing an active phased array antenna requires precise characterization of individual components and the integrated performance of the array. To ensure an accurate test of the intended adaptive nature of the active phased array antenna, the embedded algorithms need to be tested as well. This application note explains test procedures and offers recommendations towards characterization of the relevant parameters for active phased array antennas and their passive subsystem, as often used in applications for Mobile Communication and RADAR.

Automotive Ethernet: See The True Signal

As the move toward automotive Ethernet technology in vehicles accelerates, comprehensive design validation is vital to ensure interoperability and reliable operation across multiple ECUs. This application note provides information on automotive Ethernet, full-duplex communication, the need to separate master and slave signals, signal separation testing methodologies, and a comparison of the current directional coupler insertion method and the Tektronix new signal separation method.

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.

Next Generation Wi-Fi: 6 GHz Is On The Horizon

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.
