Day 1 of 2
What is RF Blockset?
Objective: Give an overview of RF simulation using MathWorks tools; the goal of this section is to familiarize the audience with RF Blockset and its terminology. Attendees who never used RF Blockset before will be able to recognize which applications can be modeled with RF Blockset and which approach is most suitable.
- Describe what can be done with RF Blockset
- Describe the benefits of using RF simulation techniques
- Articulate why and when RF Blockset is needed
Fundamentals of RF Simulation
Objective: Describe the fundamentals of Equivalent Baseband and Circuit Envelope simulation techniques. We will provide an overview of the underlying simulation techniques in the RF Blockset context. Attendees will build their first RF Blockset model, configure the simulation set up and run a simulation.
- Understand the RF simulation techniques supported by RF Blockset
- Decide when to use Equivalent Baseband or Circuit Envelope
- Build an RF model starting from high-level specifications
Importing S-Parameters and Modeling Linear Elements
Objective: Describe how to model linear elements in RF Blockset and RF Toolbox. The focus of this section is how to import S-parameters in the form of Touchstone files and how to perform a time-domain simulation using frequency-defined elements. Attendees will compare results obtained from both the Circuit Envelope and Equivalent Baseband simulation techniques for a handful of passive lumped and distributed elements, and they will gain insight into what simulation technology will work best for their application.
