This primer examines the theory of state-of-the-art spectrum analysis and describes how modern spectrum analyzers are designed and how they work. That is followed by a brief characterization of today's signal generators, which are needed as a stimulus when performing amplifier measurements.

This paper describes the basic VHV6 device structure and the enhanced ruggedness variant (EVHV6), including advantages over competing device technologies. Ruggedness expectations and requirements for RF power devices targeting ISM applications are more stringent than for devices designed for less challenging applications like cellular infrastructure. This paper will include device and design considerations that specifically target enhancing ruggedness performance. The features of the products using this platform will also be presented.

This paper discusses GaN technology, 200 W packaged device performance, a 2.6-2.7 GHz, 400 W Doherty power amplifier, thermal management, and cost vs. performance. It emphasizes how GaN and LDMOS technology complement each other for RF applications.

The Orange Book of Knowledge (OBK) has grown into much more than we at AR could have ever imagined. For many engineers, this resource book has turned into the go to source for everything and anything related to EMC. Our fifth revision includes many new application notes which will make the EMC engineers' jobs easier.

In this Understanding Guide we will introduce the basic fundamentals of the Vector Network Analyzer (VNA). Specific topics covered include phase and amplitude measurements, scattering parameters, and the polar and Smith chart displays.

This paper introduces typical configurations for EMI pre-compliance radiated and conducted emission measurements, as well as EMI design troubleshooting. You can now start from here to set up your in-house EMI pre-compliance testing.

This new application note "Solutions for Evaluating Beamforming Performance in LTE Base Stations - Using Signal Analysis and Generation to Accurately Visualize and Verify TD-LTE Beamforming Signals" is designed to help you gain insight into how to most efficiently and effectively use signal analysis and generation to accurately visualize and verify TD-LTE beamforming signals.

Vector Network Analyzers (VNA) are your primary resource when analyzing and characterizing systems and components for RF and Microwave measurements. They are regarded as accurate measuring instruments, however, quantifying the accuracy performance of a VNA in a specific application can be challenging. VNA specifications are a starting point; but, they are based upon very specific calibration and measurement conditions, which are not applicable for many applications.
