Foundry Training

MACOM offers in-depth training for RF Microwave engineers who want to learn how to design in the MACOM FAB. Basic knowledge of MMIC design and experience using Microwave Office (MWO) or Advanced Design System (ADS) is required.

This training will offer RF Microwave engineers the opportunity to:

  • Learn how to best utilize the PDK
  • Explore HEMT and passive device models
  • Understand the proper steps in designing a MMIC or HEMT
  • Follow proper procedures for submitting a design
