Publication number: 20180019715Abstract: Aspects of this disclosure relate to systems and methods of performing dynamic impedance tuning. Certain aspects may be performed by or include a dynamic impedance matching network. The dynamic impedance matching network can determine a desired output power for a power amplifier, true power information for the power amplifier, and an output power delivered to a load by the power amplifier. In addition, the dynamic impedance matching network can determine whether the output power satisfies the true power information. Responsive to this determination, the dynamic impedance matching network may modify a load line impedance for the power amplifier using an impedance tuning network.Type: ApplicationFiled: June 1, 2017Publication date: January 18, 2018Inventors: James Phillip Young, Joel Anthony Penticoff
