Modelithics® Models
Modelithics® Models for AVX RF/Microwave Components
Modelithics Microwave Global Models® reliably track how each component’s performance will change with substrate and PCB land pattern characteristics. As illustrated in the model data sheet available for each component model from Modelithics, the simulations accurately predict substrate-sensitive parasitics based on user-defined inputs of PCB board and land pattern details. A Microwave Global Model contains a complete range of values available in an AVX component family, allowing for powerful tuning and optimization of circuit designs. These advanced models for AVX components, including capacitors, inductors, resistors, attenuators, diplexers and couplers, help designers achieve first pass design success.

AVX and Modelithics® have partnered to offer FREE 90-Day trials of highly accurate, scalable advanced simulation models for various AVX parts including: Attenuators, Capacitors, Couplers, Inductors, Diplexers, Resistors.

The PCB Footprint Library is an online engineering tool created to aid in the design of your PCB layout, utilizing AVX products. Please click on the link below to download the latest library version.

RF Microwave S-Parameters & Models
RF Microwave S-Parameters & Models

AVX offers s-parameters for all of the RF/Microwave products that are offered. The s-parameter files are in standard Touchstone format and can be used with any RF software package that will allow the user to import them. They are extremely helpful when trying to model a circuit prior to prototyping and can save valuable time on the front end of your design cycle.

AVX also works with several of the most popular software vendors to ensure our products are up to date in their software, and are constantly working with new vendors to ensure that they have the most up-to-date AVX libraries. These libraries are available below and can be added to your software.
