In addition to offering advice on its halogen-free Theta materials, Rogers Corp. will be explaining the use of its free design software tool, the MWI-2010 Microwave Impedance Calculator, at the upcoming DesignCon 2011 exhibition. DesignCon is scheduled for February 1-2, 2011 at the Santa Clara Convention Center (Santa Clara, CA). Theta materials feature excellent coefficient of thermal expansion (CTE) for reliable multilayer circuits fabricated with lead-free processing.

The MWI-2010 Microwave Impedance Calculator program is available for free download from the Rogers website at www.rogerscorp.com/acm. Working on any Windows personal computer, the software calculates key transmission-line parameters based on the use of Rogers' high-frequency circuit materials. It can calculate parameters for microstrip, stripline, and even coplanar waveguide (CPW) transmission lines. For more on the software, don't miss the Product Feature in the February 2011 issue of Microwaves & RF.
