Modelithics® is a leading-edge technology company that provides highly accurate, scalable measurement-based simulation models for all types of RF and microwave devices, as well as comprehensive RF and microwave measurement services.

Modelithics models are compatible with many popular EDA tools including Keysight ADS, Cadence AWR Design Environment, Keysight Genesys, Ansys® HFSS™, Sonnet® Suites™ and Cadence® Spectre® RF. The models capture parasitic effects of RF and MW components, and offer scalable design parameters, such as substrate scaling, pad scaling and part value scaling, plus adjustable input parameters such as bias and temperature for active device models. The advanced features provide for powerful design analysis capability, which increases design accuracy and helps lead to rapid design success. Modelithics also offers a collection of full-wave 3D EM models for use with Ansys HFSS.

Through the Modelithics Vendor Partner Program (MVP), Modelithics collaborates with RF component and semiconductor device manufacturers by developing top quality models for their products. Extensive characterization and modeling services are offered, including capabilities for custom 3D model development, GaN modeling, X-Parameters, load pull and noise measurements. Modelithics has also recently launched a new Standard & Custom Test Fixture and Accessory Product Line, including legacy parts from J Micro Technology for a family of thin film Alumina substrate components.


For over 30 years, Aerospace Consulting has been serving the RF, microwave, high speed analog, Iot, antenna design, and embedded system world. As you may know, RF and wireless design is complex and requires complex, expensive software and test equipment, along with the experience necessary to know how to properly use that software and test equipment. Aerospace Consulting has all of the necessary software including:

Keysight ADS for RF and microwave circuit simulation, design, and optimization, including load-pull for high power amplifier design.

Keysight Genesys for RF and microwave circuit and system design, including oscillators, filters of all sorts, and optimization.

Keysight SystemVue for digital system design and system simulation.

Modelithics passive and active component libraries for super-accurate simulations that include things like the effect of component mounting pads and board dielectric constant.

Matlab for general math and simulation.

Mathematica for general math.

Altium Designer for circuit board design and Spice simulation.

SolidWorks for 3D design

Intusoft Intuspice for Spice circuit design.

And, many other programs, along with experience with Keysight EMPro for 3D EM simulation, AWR Microwave Office, CST Microwave studio, Ansys programs, including HFSS.
