What is AppCAD?
AppCAD is an easy-to-use program that provides you with a unique suite of RF design tools and computerized Application Notes to make your wireless design job faster and easier. AppCAD’s unique, interactive approach makes engineering calculations quick and easy for many RF, microwave, and wireless applications. AppCAD is useful for the design and analysis of many circuits, signals, and systems using products from discrete transistors and diodes to Silicon and GaAs integrated circuits. The keyword for AppCAD is easy – no circuit files, no manuals – just quick and easy.
AppCAD is updated with new features as time permits. This web site will always have the latest downloads and version information.
The AppCAD Story
The Application Engineering staff of the Microwave Semiconductor Division of Hewlett-Packard created AppCAD as a design help for RF & Microwave (a.k.a., wireless) designers. AppCAD was then, and still is, distributed free of charge as a service to the wireless engineering community.
AppCAD was originally released in 1990 by Hewlett-Packard as version 1.02 (the “Classic” version). Version 1.02 was a DOS program that was compatible with Windows 3.x. Although based on the original MS-DOS® version of RF and Microwave AppCAD “Classic,” the current version of AppCAD runs on 32-bit Windows® operating systems and contains many new and innovative design programs.
In 1999, Hewlett-Packard split into two companies, with the computer-related business retaining the Hewlett-Packard name ($49 billion revenue, 88,500 employees) and the test, measurement, semiconductor, and chemical analysis business sectors becoming Agilent Technologies ($11 billion revenue, 47,000 employees). At this time, the Microwave Semiconductor Division of HP become the Wireless Semiconductor Division of Agilent Technologies, which retained the AppCAD program.
In 2005, Agilent spun its semiconductor sector, including the Wireless Semiconductor Division, off into a new company named Avago Technologies ($2 billion revenue, 6,500 employees).
