Data-based Load Pull Amplifier

Posted on Feb 4, 2014

The AmpLoadPull project illustrates the use of the AmpLoadPull and LoadPullSetup components in ADS. These components are part of the ADS behavioral model suite found under the System - Data Models palette. `circuit_level_amplifier_1_tone. dsn` is a schematic for a circuit level 1-tone fixed input power swept reflection coefficient harmonic balance simulation of the amplifier.

The result is in the dataset "circuit_level_amplifier_1_tone. ds. " "behavioral_level_amplifier_setup. dsn" is a schematic using LoadPullSetup for the generation of the behavioral model for the amplifier. The result is in the dataset "behavioral_level_amplifier_setup. ds. " "behavioral_level_amplifier_1_tone. dsn" is a schematic for a behavioral level 1-tone fixed input power swept reflection coefficient harmonic balance simulation of the amplifier of interest using AmpLoadPull along with the dataset "behavioral_level_amplifier_setup. ds. " The result is in the dataset "behavioral_level_amplifier_1_tone. ds. " In Figure 1, a comparison of circuit and behavioral level results is given for a Harmonic Balance loadpull analysis. Specifically, results for power delivered to the load and power added efficiency are given for both a 50 Ohm and 10 Ohm reference impedance. The agreement is generally good.
