H2ID Waveform Atlas – Version 2B
This Atlas provides practical knee-aware complementary waveform solutions for RF power amplifiers operating with second-harmonic input distortion. Instead of performing extensive harmonic-load exploration, designers can directly identify high-efficiency operating points, waveform shapes, and associated harmonic terminations across the H2ID design space.
The atlas can save weeks of harmonic-load exploration and waveform synthesis work.
What is New in this Atlas?

Waveform-centric rather than class-centric methodology.
-
Complete exploration of H2ID space.
-
Knee-aware solutions.
-
Harmonic impedances included.
-
Discovery of non-classical operating modes.
-
Identification of design avoidance regions.
-
Practical implementation guidance.

KEY INSIGHTS
-
Efficiency depends on H2ID magnitude and phase.
-
Different power factors for the different sets of complementary waveforms. Two operating points with similar efficiency may differ significantly in obtainable output power.
-
Trade-off between power and efficiency because of the transistor knee at each operating point.
-
Some regions must be avoided.
-
90% efficiency achievable at some operating points.
WORKFLOW
-
Select H2ID operating point based on efficiency and power factor
-
Decide on knee power versus efficiency compromise and scale waveforms accordingly
-
Calculate intrinsic impedances
-
Map intrinsic impedances to the external reference plane
-
Implement & tune
