Genesys Products - Advanced Transmission Line Synthesis Module

Japan	Korea	Taiwan	China	Russia

Genesys Advanced T/Line Synthesis accelerates virtual prototyping and fabrication by mapping a whole distributed RF circuit schematic to one of 13 other physical model sets using only a couple of mouse clicks. It also saves time and engineering costs by converting existing physical designs to other dielectrics and processes, while preserving the original electrical length and impedance. This facilitates design re-use and second-sourcing of boards with other fabrication vendors, while minimizing re-work.

Convert a whole design in one command

Advanced T/Line Synthesis bridges the gap from ideal transmission lines and Smith Charts to fabrication processes by converting whole schematics in a single command. Component by component, it calculates the impedances and dimensions, and replaces each item in your schematic with a physical model having approximately the same characteristics, and accounting for dispersion, skin effect loss, and conductor thickness. For some cases, it also adds the associated discontinuity model and adjusts the length of the attached line to compensate for the parasitic.

Re-use and Re-deploy circuits faster

Advanced T/Line synthesis also converts existing designs back to ideal transmission lines, or between substrate configurations. This is a powerful option for updating an older design, changing a manufacturing process or board stack-up, or sending a design to alternate board vendor. It also makes it possible to change the targeted center frequency of that part of the design, to move a filter to a slightly different frequency.

For example, you may have created a double-stub network on a 25mil thick substrate. You now want to use a thinner10mil substrate. Advanced T/Line can convert the original microstrip widths to the widths necessary to maintain the impedances on the new substrate material, doing so for each component.

Put away your transmission line calculator - Advanced T/Line Synthesis is a convenient productivity tool you will never want to be without!

How is Genesys Advanced T/Line Synthesis made available?

• The W1508L Genesys Advanced T/Line Synthesis module can be easily added to any particular Genesys environment or license key that is current on maintenance.
• The older T/Line Synthesis module, a simple transmission line calculator, is now included for free with Genesys Core.
• Advanced T/Line Synthesis is included in the Designer Pro, Integrated, and Virtual VNA bundles
• It is also included in the Genesys Synthesis for ADS and RF Architect for ADS bundles
• Advanced T/Line Synthesis was also included in several older Genesys configurations, which your company may already own. (W1403, W1404, W1405, W1406, W1412, W1413, W1414). Refer to the Bundle Viewer for more details.

How Genesys Advanced T/Line Synthesis interacts with other modules

• Genesys Core is the only software requirement for Advanced T/Line Synthesis.
• The capability from Advanced T/Line Synthesis is borrowed by M/Filter, Match, and Signal Control Synthesis for use on their respective circuits. If you own Advance T/Line Synthesis, you have full functionality for all circuits outside of the synthesis user interface.
