AWR Software 8 www.cadence.com/go/awr Applications and Technologies RF System Models RF system models include RF behavioral, file, and circuit- based models that quickly perform frequency-based cascaded measurements such as cascaded NF or operating gain or identify the makeup of frequency content at any point in an RF link using the RFI tool. RF modeling applies to the portions of a system design that represent analog voltage signals, usually at RF frequencies but not always. These are the portions of the design that include behavioral amplifiers, mixers, and circuit-based filters, as well as blocks for incorporating AWR Microwave Office circuit designs within a system simulation. Communication PAs Preconfigured testbenches supporting the latest 5G signals and frameworks proposed by various industry groups allow designers to simulate and optimize the performance of RF front-end components such as PAs based on PAPR, adjacent channel leakage ratio (ACLR), EVM, or any number of critical amplifier performance metrics, as well as identify the source of spurious products and other system impairments. System- level load-pull analysis generates contours for communication performance metrics such as ACPR and EVM, allowing designers to optimize impedance-matching networks for linear PAs used in wireless communication systems. Phased Array Generator The phased array generator wizard within AWR VSS software enables designers to interactively design a phased array antenna and then generate schematics or system diagrams that represent the design. Quickly configure planar phased array or multiple-in-multiple-out (MIMO) array systems, interactively modify designs to achieve the desired behavior, and generate system diagrams and/or circuit schematics and EM structures for further, more rigorous analysis. The wizard supports interactive specifi- cation of the layout, feed network settings, element antenna and RF link settings, gain tapers, and element failures. The unique, open, and integrated environment of VSS enabled us to study the effects of the nonlinear distortion on our communications link margin using real digital modulated analog waveforms.
