Designing RF systems to operate with wideband modulated signals, like 5G and RADAR, or with a large number of circuits, like active antennas, is challenging. AMCAD Engineering introduces new behavioral models for power amplifiers that include low and high-frequency memory effects allowing robust and accurate DPD algorithm evaluation and validation.

This article will provide a top-level view of Wolfspeed's large-signal models for GaN power transistors and their application in an RF design. The article will include an overview of Wolfspeed's GaN on SiC devices, the associated large-signal models, and their advantages versus real-world devices during the development process. The piece will continue with an overview of a typical design procedure and a case study, then conclude with a discussion of the resources available to designers and how to get started.

Your challenge: Testing coexistence and user experience to ensure high quality of service in real-world use, and ensuring security and product compliance for risk free market introduction. Rohde & Schwarz is a one-stop shop catering to all wireless RF coexistence test and measurement requirements.

On Saturday, May 30th, people across the world watched in awe as SpaceX launched a rocket, designed independently of any government, putting two astronauts into orbit on their way to the International Space Station — the first time in history for any commercial company. Ten years ago, this would have been an unthinkable endeavor for any commercial or private organization.

A Vector Network Analyzer (VNA) natively measures complex S-parameters of a device under test (DUT) in the frequency domain mode by sweeping across various frequency points. While there is an exhaustive list of measurements that can be accomplished in the standard frequency domain mode – using the advanced inverse Chirp z-transformation, the measurements can also be simultaneously analyzed in the time domain mode. This gives the added advantage where the two fundamental modes of analysis can be performed by one single instrument.

5G implementation is accelerating and the promise of higher data rates means more challenges. Demand for more bandwidth increases the probability of interference in mobile devices, driving the need for advanced filtering. Qorvo's BAW filters have evolved to address higher frequencies in shrinking RFFE real estate, while maintaining RF output power.

Future technologies and standards will make over-the-air (OTA) testing mandatory. Measurement requirements will change and engineers need a basic understanding of antennas and antenna measurements. But how to get ready for OTA testing? Learn more with our extensive white paper.
