Modulated RF analysis for circuit and system design

May 28, 2014 // By Graham Prophet
Agilent Technologies’ Genesys 2014 RF simulation and synthesis software offers an affordable, accurate, easy-to-use medium in which to analyse digitally modulated RF signals. This release of the Agilent EEsof EDA software features breakthrough modulated RF analysis as well as enhancements to its powerful, custom-filter direct synthesis technology.

Using Genesys 2014, designers can simulate digitally modulated RF signals such as those found in today’s defence and consumer wireless applications as easily as they do traditional analogue RF signals. Unlike other simulators that provide only single-value results for EVM, BER or ACPR, Genesys 2014 delivers breakthrough system budget analysis of these digital modulation metrics for every component in the system block diagram, all in a single pass. This provides RF designers with the ability to immediately identify culprit components causing digital performance failures.

Underlying Genesys 2014’s accurate digital modulation analysis is a new, embedded numeric dataflow simulator that also enables easy verification against the latest wireless standards for WLAN 802.11ac and LTE-3GPP. With the appropriate defaults conveniently set up and ready for use in the software’s test menus, RF designers no longer need struggle with setting unfamiliar and complex dataflow parameters to verify their circuits or systems against wireless standards.

“When designing the new Genesys 2014 modulated RF capability, we wanted to make it extremely intuitive for RF designers,” said How-Siang Yap, Genesys product planning manager with Agilent EEsof EDA. “We accomplished this goal by mimicking what RF designers already do on the bench with vector sources and analysers. Genesys 2014 is now able to automatically take care of all the complexity of dataflow sources, sinks and their parameters behind the scenes.”

Genesys 2014 updates its direct-synthesis technology for seamless workspace integration to allow multiple custom filters to be interactively designed together. Doing so enables the exacting design of diplexers, multiplexers and notched filters. Powerful equivalent network transforms can then be used, allowing designers to realise their designs in lumped and/or distributed printed circuit boards.

This release also features the largest collection of vendor X-parameters models for use in nonlinear circuit and system simulation. Additional upgrades to Genesys 2014 include a new Momentum planar electromagnetic simulator and 3D layout viewer, an improved phase noise simulation algorithm, and 100% MATLAB
