ADS Fundamentals - 2001 LAB 2: System Design Fundamentals Overview - This chapter introduces the use of behavioral models to create a system such as a receiver. This lab will be the first step in the design process where the system level behavioral models are simulated to approximate the desired performance. By setting the desired specifications in the system components, you can later replace them with individual circuits and compare the results to the behavioral models. OBJECTIVES Use the skills developed in the first lab exercise. Create a system project for an RF receiver using behavioral models (filter, amplifier, mixer) where: RF = 1900 MHz and IF= 100 MHz. Test the system: S-parameters, Budget, Spectrum, Noise, etc. Lab 2: System Design Fundamentals Table of Contents 1 Create a New Project and schematic. 3 2. Build a behavioral RF receiver system. 3 3.
