A Comparison of GaN vs. GaAs System Performance

Traditionally RF power amplifiers used GaAs technology which has a well behaved and understood performance. Over the past few years GaN technology is replacing GaAs because GaN is more efficient and has a higher power density resulting in higher power MMICs and FETs.

App Note: Transmitter Test: Overcoming Five Fundamental Challenges

Development of any wireless system is a demanding task, bounded by tight constraints and complicated by innumerable tradeoffs. This application note offers solutions that will help you overcome fundamental challenges in transmitter testing, including standard-compliance, power measurements, interference, EMC, and power consumption.

White Paper: 5 New Features and Test Challenges on 802.11ax

The new 802.11ax standard (High Efficiency or HE specification) aims to provide better spectral efficiency, capacity, and coverage in dense deployment scenarios as well as outdoor environments, with a goal to improve the average throughput per station by at least 4x compared to 802.11ac. Let’s look at five new features in 802.11ax that enable these improvements.

The Challenges of Using Direct Reading Attenuators and Current Solutions

One of the most challenging things about working with millimeter-wave technology is getting accurate measurements. Uncertainty can be introduced at many points during testing, so selecting the right test equipment is an important decision.

5G Antenna Design for 5G Communications

While some of the challenges that lie ahead to meet the 5G requirements may seem daunting, simulation can already be used to develop understanding and explore innovative solutions. Altair FEKO offers comprehensive solutions for device and base station antenna design, while WinProp will determine the requirements for successful network deployment.

Millimeter-Wave Beamforming: Antenna Array Design Choices & Characterization

This paper introduces the fundamental theory behind beamforming antennas. In addition, calculation methods for radiation patterns with simulations results, as well as some real world measurement results for small linear arrays are shown. Due to the likely bandwidths in such applications, a non-standard way of graphical representation is proposed.

When Choosing Test Equipment, Don’t Forget the Interface

The software interface is an often overlooked, yet critical item in putting together a test system. It’s not enough for a piece of equipment to work well in isolation. In a production environment it must interact with and take commands from other modules, and in a laboratory setting it must work seamlessly with multiple hosts. Understanding some of the potential interface barriers and how to remove them is an important first step before evaluating any piece of test equipment.

LTE-Advanced Pro Introduction eMBB Technology Components in 3GPP Release 13/14

Concrete and confined use cases such as mobile voice in 2G and mobile data in 4G dominated the definition of past cellular technologies. In contrast, 5G introduces a paradigm change towards a user/application centric technology framework that aims to support the following triangle of important use case families. The enhanced mobile broadband (eMBB) use case represents the well-known continuation of the ever-increasing requirement to support both higher peak data rates per user and more system capacity.
