Maar ooit in de HP tijd heeft men een leuk tooltje uitgebracht voor het nodige RF rekenwerk. Deze tool onder de naam AppCAD kan het volgende:...
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.
En de tool is gratis te downloaden vanaf:...
