Wideband, High-Power GaN PAs in SMT Packages Preserve Electrical and Thermal Performance While Simplifying Design

This paper discusses gallium nitride as the preferred technology over gallium arsenide for facilitating power levels up to 10 watts and providing superior performance with simpler handling and assembly requirements. Topics include circuit design implications for these higher power levels, surface mount packaging for simplified design, performance examples and applications.

5G Evolution – On the Path to 6G: Expanding the Frontiers of Wireless Communications

3GPP 1) defined the fifth generation (5G) cellular technology in Release 15 to meet ITU’s IMT-2020 2) performance requirements and to enable a variety of services associated with usage scenarios such as enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC) and massive machine type communications (mMTC).

Advanced BAW Filter Technology and Its Impact on 5G

Global rollouts of 5G, and the expansion of the Internet of Things, creates significant new RF filtering challenges and Qorvo’s bulk acoustic wave (BAW) filters have advanced to solve them. They’ve evolved to support higher frequencies and increased bandwidth, utilize complex multi-filter modules, and mitigate the small form factor dilemma.

Behavioral Modelling Challenges for RF System Simulation

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.

Analog Devices Advances RF/mW in The Space Industry

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.

Time Domain Analysis with a VNA

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.

A New Generation of 5G Filter Technology

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.

5G Evolution – on the Path to 6G

5G is now - what´s next? 5G deployments have only recently started, and releases beyond R15 will continue to tap into the tremendous potential of 5G. However, as a new generation of cellular technology typically appears every 8-10 years, 6G can be expected around 2030. Download this white paper to explore the evolution from 5G to 6G from a service, air interface and network perspective.
