Enhancements to Agilent ADS’s Load Pull DesignGuide Andy Howard, 2/23/2012 After the ADS 2011.10 release, we have updated the Load Pull DesignGuide. We have added several simulation setups and re-organized the menus to make them easier to navigate. This document discusses what is new. This is the new menu structure: 1 © Copyright Agilent Technologies, 2012 This shows some of the selections under the main menu selections: The (Maury) –Find Optimal Load for Specified Output Power and the selections under Mismatch Analysis are new. 2 © Copyright Agilent Technologies, 2012 These are the rest of the menu selections, including the new ones under Mismatch Analysis: 3 © Copyright Agilent Technologies, 2012 The (Maury) –Find Optimal Load for Specified Output Power setup reads in measured load pull data and finds the optimal load (for maximum efficiency) for each target output power that you specify. This is the Find_Optimal_Load_For_Specified_Pout schematic: 4 © Copyright Agilent Technologies, 2012 This shows the results, after running an optimization: 5 © Copyright Agilent Technologies, 2012 Selecting Mismatch Analysis Constant Available Source Power inserts a copy of the Load_Mismatch_Sweep simulation setup. This is for investigating how a device or amplifier’s performance degrades as the load VSWR (relative to an optimal impedance) and reflection phase are swept. This setup allows you to specify the optimal load impedance at the fundamental frequency, as well as the impedances at the harmonics. The available source power in dBm is fixed.
