1. A system configured to deliver wireless charging power, the system comprising:
an electronic computing system; and
a high-power electromagnetic radiation generator configured to generate an electromagnetic charging beam to charge an electronic target, the high-power electromagnetic radiation generator comprising:
a programmable radio frequency (RF) generator configured to generate an RF signal with a central frequency in a range from about 0.25 GHz to about 20.04.0 GHz;
a plurality of amplifying systems configured to amplify the RF signal, the plurality of amplifying systems each comprising a plurality of solid-state amplifiers; and
a plurality of power management systems configured to apply first gate bias voltages provided to the plurality of solid-state amplifiers in response to receiving a signal indicating that the RF signal will be input to the plurality of amplifying systems, the plurality of power management systems further configured to apply second gate bias voltages to the plurality of solid-state amplifiers in response to receiving a signal indicating that the RF signal will not be input to the plurality of amplifying systems.
