EXPERIMENT NO:01
AIM: Introduction to APPCAD.
APPARATUS: APPCAD software.
THEORY: 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 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.
Everything S-parameters is the quick and easy way of analyzing S-parameter data for devices or
circuits to obtain key performance parameters such as gain, stability, reflection loss, and
matching impedances.
A unique feature of AppCAD's Everything S-Parameters is the ability to load up to 3 sets of SnP
files and make side-by-side comparisons.This side-by-side comparison feature is exceptionally
useful for comparing different devices to assist with design-in decisions, or analyzing the same
device under different conditions, e.g., three different bias currents or temperatures. This feature
is also useful for looking at circuit performance before and after design changes.
Also unique to AppCAD's Everything S-Parameters is the 2-Port Single-ended to 1-Port
Differential Impedance conversion. This function converts of a set of conventional, 2-port,
single-ended S-parameters into a 1-port differential impedance. This feature is very useful for
measuring balanced circuits with a standard vector network analyzer.
Everything S-parameters can analyze over 40 different parameters covering:
