Genesys Products - S/Filter Synthesis Module

  Japan

Genesys S/Filter Synthesis allows RF component designers and system architects to maximize system performance with high-performance custom filters, while minimizing time, effort, prototyping, and system cost. S/Filter Synthesis is practical, easy-to-use, and adds economically to any RF design flow, including non-Agilent EDA tools.

A professional tool, with the elegance and affordability of Genesys

RF engineers use S/Filter Synthesis to quickly create elegant, high-value designs. S/Filter Synthesis quickly transforms generic filter types into practical, high-performance circuits that eliminate specific spurs, minimize parts count, avoid problematic parts values and topologies, account for finite Q, and much more.

While other synthesis tools provide poor EDA integration, a narrow set of filter types, or unfriendly mathematical approaches to filter design, S/Filter Synthesis is more suited to the needs of the RF community. It is easy to use and practical, with extensive online documentation. It provides a wide range of design flexibility with nearly 200 topological transforms, thus balancing automation and convenience with the RF engineer's need to control every aspect of a high-performance design. S/Filter Synthesis uses sophisticated mathematics to provide direct synthesis of a custom filter response.

High-level of integration

The output of S/Filter Synthesis is a standard schematic within the Genesys environment. Since S/Filter Synthesis designs are no different from any other Genesys subcircuit, the physical implementation of the design can move forward at any time by applying SMT library parts, layout tools, and statistical and high-yield design techniques, then verified with a rich variety of time-domain, frequency-domain, system, and accurate EM simulators. If this verification shows that you need to modify the filter design, you simply re-open the S/Filter Synthesis window, and continue improving the filter. With filter tables, standalone utilities, and even 3rd party add-ons, you lose design flexibility and the ability to iterate quickly within the context of a larger design flow.

High-performance filters that solve real problems

For designers who concentrate on filter design, S/Filter Synthesis goes beyond filter tables to solve more practical problems, while bridging the divide between lumped and distributed techniques in the wireless frequency bands. S/Filter allows you to build a custom frequency response, then choose among different implementation alternatives, while manipulating and transforming portions of the filter to solve design problems, reduce parts count, make the design more manufacturable and less sensitive.

S/Filter Synthesis includes these features to make you successful:

• RF awareness – familiar terms and settings for RF designers
• Build the narrow or wide frequency response you want to achieve, then add specific zeroes to suppress unwanted frequencies
• Real-time automated synthesis of a wide variety of candidate filters, which can be sorted by 26 characteristics such as Minimum Inductor Value, Cmax/Cmin ratio, and more
• Nearly 200 lumped & distributed topological transforms are ready customize a filter candidate to make it more simple, easier to build, less sensitive, and fewer parts
• Direct integration with the Genesys design environment, including simulators, parts libraries, optimization, and high-yield design support, layout, and graphics export
• Export designs to ADS or other EDA environments
• Extensive documentation and online Help
• Also includes Filter Synthesis (lumped) and M/Filter Synthesis (distributed), for creating standard filter types

What is included with S/Filter Synthesis?

S/Filter Synthesis is itself a Genesys bundle that includes

• W1501L Filter Synthesis for standard lumped-element filters
• W1502L M/Filter Synthesis for standard distributed-element filters
• Additional interactive capability for producing custom filters that solve specific high-performance design challenges

How is Genesys S/Filter Synthesis available?

S/Filter Synthesis can be added to any existing Genesys environment. Genesys Core is the only software requirement for S/Filter Synthesis.

If you do not currently have an environment, or wish to use S/Filter to augment your main RF EDA environments, Agilent recommends the W1411L Designer Pro bundle. The W1411L Genesys Designer Pro includes Genesys Core and all 11 Genesys synthesis modules (including S/Filter Synthesis), along with the first 12 months of support, for under $10,000 (US List).
