RF microwave CAE CAD
RF microwave CAE CAD is computer-aided design (CAD) using computer technology to aid in the design, modeling, and simulation of an RF (Radio Frequency) or microwave product.[https://ieeexplore.ieee.org/document/1127005/ J.W.

Scope of design
RF and microwave circuit design and simulation software for the electronic design automation (EDA) marketplace includes but not limited to circuit simulation, analysis, schematic capture, and integrated design environment for synthesis tools which automate the design of HF (high frequency) circuits from RF to microwave to millimeter waves. Physical modeling of stripline and microstrip for transmission lines. A wide range of applications are possible, from analog sub-circuit design to RF circuit design for complex wireless communications systems.{{Cite journal|title=An integrated overview of CAD/CAE tools and their use on wireless-communication circuit design: Research Articles|journal=International Journal of RF and Microwave Computer-Aided Engineering|date=November 2004|volume=14|issue=6|pages=507–524|last1=Pedro|first1=José Carlos|last2=Carvalho|first2=Nuno Borges|doi=10.1002/mmce.20039|doi-access=free}}
Scope of modeling
There are a vast number of device or component types which can be simulated in computer aided design software. Generally, the degree of complexity for modeling depends on the software package and the synthesis of off-the-shelf models and application-specific custom models. The component types can be categorized as follows: amplifiers, antennas, attenuators, cabling, capacitors, circulators, combiners, couplers, connectors, DC blocks, delay lines, detectors, diodes, dividers, ferrites, filters, inductors, isolators, limiters, mixers, oscillators, phase shifters, resistors, rotary joints, switches, transistors, terminators, and waveguides.
