Segmented RF Power Transmitter Center-Out Activation for Linear Output

The patent applies asymmetry by reversing the conventional activation pattern: instead of activating segments from outer edges inward, the invention activates segments from the center outward. This asymmetric activation approach balances current redistribution effects across the segmented output stage, eliminating irregularities in the CWD-to-RF output signal transfer while maintaining straightforward implementation logic.

The patent changes the temporal parameter of segment activation by introducing multiple activation moments within each RF cycle. By strategically timing when different segments are activated and by combining this with center-outward activation ordering, the system achieves smooth RF output waveforms while minimizing harmful current redistribution effects that would otherwise degrade performance.

The patent applies preliminary action by implementing digital pre-distortion that compensates for linearity imperfections before the signal undergoes segmentation and multiple activation moments. By pre-correcting the input signal characteristics based on anticipated distortion from the segmented architecture, the system achieves high spectral purity while keeping the pre-distorter algorithms relatively simple and manageable.
