Thermal Management of RF and Digital Electronic Assemblies using Optimized Materials and PCB Designs

The main objective of this paper is to provide a greater understanding and appreciation of challenges posed in efficient thermal management of electronic assemblies and how to figure out an optimized solution in terms of cost, volume production, product performance and reliability.

Subminiature, Low-power DACs Address High Channel Density Transmitter Systems

The volume of broadband data transmitted in cable systems has increased tremendously over the last decade. Since 2003, the number of subscribers to broadband data cable services has increased at a compound annual growth rate approaching 14% [1]. The annual growth rate has since slowed, but recent trend information shows double digit growth in premium, soâ??called "wideband" broadband services.

Spectrum Analyzer Fundamentals-Theory and Operation of Modern Spectrum Analyzers

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.

50V RF LDMOS - An Ideal RF Power Technology for ISM, Broadcast and Commercial Aerospace Applications

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.

Gallium Nitride RF Technology Advances and Applications

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.

Orange Book of Knowledge - V

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.

Understanding Vector Network Analysis

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.

Accelerate EMI Identification During Troubleshooting and Design Verification

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.

Solutions for Evaluating Beamforming Performance in LTE Base Stations

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.

Calculating VNA Measurement Accuracy

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.
