Introduction
Harmonic Load Pull improves PAE.
Linearity effects are now investigated.
Accuracy of a load pull system needs verification.
Delta-Gt method for Load, Source, & Harmonic Tuners.
Compare small-signal ANA measurements.
Power sweep ANA vs. 50Ω Load Pull compression.
CAE linear and non-linear model comparisons.
Load Pull results quantify Non-Linear model sims.
Maury Microwave ATS Bench Setup
The Triplexer S-Parameters are created by measuring each signal path.
Tuners are characterized at 2.45GHz, 4.9GHz and 7.35 GHz.
S-Parameter blocks <S> accounted for the DUT Probes.
Short Low Loss cables connect Cascade Probes.
