Researchers at Stanford have developed a method to tune power amplifier circuits to directly connect their output power (and adjust the combined output power) without any additional power combiner network.
This single-stage resonant inverter architecture achieves constant power and efficiency over a large bandwidth, solving one of the largest problems with state-of-the-art resonant inverter power amplifier architectures.
Researchers in Dr. Juan Rivas-Davila's lab have developed 3D printing methods to make aircore inductors and capacitors with more complex geometries and functionality than components using printed circuit boards.
