VISUAL SYSTEM SIMULATOR
RF Architectural Tool
AWR RFA™ software, is a system-level architectural planning tool, which provides an advanced radio frequency (RF) budget analysis feature and “frequency heritage inspection” capabilities for next-generation communication design. This new entry-level product is the latest addition to the company’s Visual System Simulator™ (VSS) design suite.
RFA™ is an advanced system-level planning and specification tool for RF communication system engineers who need to quickly create and verify the initial specifications of a radio design. The product helps find potential pitfalls early in the design process, at the system-level design phase, thus saving significant design cycle time and speeding products to market. RFA has been developed with the same overriding goal as all AWR software products—to provide engineers with the ability to explore design options and gain further insight into their designs so that they can produce quality products efficiently.
The RFA tool delivers several new technologies that enable communications designers to streamline their product development process. One key component of RFA is the RF Budget Analysis™ feature that provides the ability to make traditional RF cascaded measurements such as gain, noise figure, and third-order intercept, inclusive of image noise, along a communication link.
The RF Inspector™ technology, another component of RFA, is a new frequency-domain simulation tool that helps determine the root cause or heritage of any intermodulation product of an RF link and includes the effects of conversions, harmonics, and intermodulation. In addition, effects of thermal noise, and phase noise are accounted for. This enables users to isolate the sources of unwanted interferers and to better architect their RF systems.
The RF inspector interface provides a clean and efficient means of determining the individual contributions to a particular tone. Flags of different colors are used to easily allow the user to identify the desired signal, intermodulation products and distortion products. Engineers can take their designs one step further by using the complete VSS product to perform EVM, ACPR or BER analysis. Traditional RF/analog system analysis commonly requires several tools to achieve a complete analysis of end-to-end performance.
