MWI-2010 Microwave Impedance Calculator is available for free download at www.rogerscorp.com/acm. Is supplied as an executable file that will run on any Windows-compatible PC. Provides quick calculations of key transmission-line parameters based on the use of extensive lines of high-frequency circuit materials. Uses closed-form equations; can calculate the impedance of high-frequency conductors based on a variety of transmission-line technologies, including microstrip and stripline, and laminate materials. Provides on-screen menus in selections of transmission-line technology, material, material thickness, conductor thickness, and other parameters. Menus list materials and relative dielectric constants, dissipation (loss) factors, thermal conductivity, and thermal coefficient of dielectric constant.
