S参数模拟4 This chapter shows how to make S-parameter simulations and how to determine matching network values. Lab 4: S-parameter Simulations Lab 4: S-parameter Simulations OBJECTIVES Measure gain and impedance with S-parameters Use a sweep plans, parameter sweeps, and equation based impedances Plot and manipulate data in new ways About this lab: This lab continues the mixer testing by making various S-parameter measurements to determine circuit performance: gain and impedance. PROCEDURE 1. Copy the last lab and save it as a new design named: s_params. After saving the schematic as s_params, continue modifying the design to match the schematic shown here, according to the following steps: a. Delete the AC sources and simulations. Also delete the measurement equations, parameters sweep, e……
