With continued pressure for increased 3G coverage for smart phones, increased Internet connection for Wi-Fi and WiMAX, and the imminent introduction of 4G/LTE systems, design activity for digital communication RF components has never been greater. At the forefront of the design activity is the development of power amplifiers (PA).
This white paper examines the different nonlinear models and measurement systems available today and how they can be used with Microwave Office®, a leading high-frequency design environment from AWR Corporation.
As technology has advanced, tools have been developed that go beyond merely analyzing devices to tools that design devices. These tools allow the user to select basic structures with variable dimensions, size constraints, and performance goals and then iterate automatically until the best possible design is found. The user is freed from the burden of monitoring the progress of each individual simulation and can devote time to other tasks. This evolutionary step in simulation software is improving the productivity of engineers developing nextgeneration devices in a variety of fields.
This application note describes the R&S ZVA_110 converters, which extend the frequency range of the R&S ZVA family of vector network analyzers to cover the millimeter-wave range.
In building a strategy for effective integrated-circuit design, it is important to understand the characteristics of different RF and microwave printed beam forming networks (BFN). Optimization of the design process for BFN can reduce unnecessary costs and design iterations, thus allowing designers time to improve the quality of the product. The design process includes various stages from analysis of requirements to final design documentation, balancing and trading off factors such as electrical performance, size, cost, etc.
