This Web-based “inductor finder” makes quick work of finding and sorting all of the company’s products that fit a user’s requirements. Enter the inductance and operating frequency plus any other critical parameters like SRF, DCR, Q, mounting and dimensions. The program returns a detailed table of suitable inductors complete with specifications. A user can sort on any field to make easy comparisons based on key parameters. A click on any part number brings up the complete Web page where a user can view performance graphs, request samples, download SPICE models and S-parameters, and view pricing. Other tools on the company’s Web site help a user select DC-DC converter inductors and find crosses to competitors’ parts.

Chip Packaging Toolkit
The release of the chip packaging toolkit option for Pulsonix PCB design software targets chip packaging and chip-on-board designers. The toolkit provides the option to create and annotate die, bond pads and bond wires, and also allows the automatic placing of bond pads around bare die components. On-line design rule check (DRC) and batch design rules can be set for minimum and maximum length of the bond pad from the die pad, and for crossing over of insulated and non-insulated wires.

Microwave Impedance Calculator
The MWIJ (JAVA version of the MWI program written by G.R. Traut) applet allows the user, for a given impedance (or vice versa), to calculate transmission line losses and temperature rise, and obtain line widths and calculations for stripline and microstrip circuits through the use of a JAVA enabled browser.

Interactive Cable Finder
To provide a measure of application engineering that is available on the user’s schedule, the microwave portion of the company’s Web site includes an interactive cable finder that walks the user through a range of configuration options to arrive at a best-fit flexible or semi-rigid cable product. The cable finder provides a part number, various performance data, and basic cable construction and armoring images and descriptors. An insertion loss (IL) calculator (for flexible assemblies) further customizes product data by computing IL at user-specific frequencies and temperatures. To begin an interactive search, go to www.stormproducts.com/microwave and click on “FIND A PRODUCT.”

D2G Software Product
This DXF software product D2G is for the RF and microwave industries. The IsoPro’s DXF import from a wide range of CAD packages (including AutoCAD) allows RF and microwave engineers to quickly edit, prototype and produce quality antenna and microwave circuit boards. In addition, IsoPro’s advanced Polygon support (including nesting and sorting layer polygons) has proven especially useful. At $495.00 and upgrades for $195.00, a user has the ability to read and edit DXF files from any version of AutoCAD. IsoPro/D2G is available in a number of languages including English, Spanish and Japanese.
