1. A high-power pulsed electromagnetic field (PEMF) applicator system, the system comprising:
a base housing comprising a controller configured to generate and multiplex a high-power pulsed signal, the base comprising a tuned switching power amplifier comprising a single-pole switching element configured to generate a pulsed drive signal, and a plurality of RF amplification stages; and
two or more applicators coupled or configured to couple to one of the RF amplification stages of the plurality of RF amplification stages in the base housing, wherein each applicator comprises:
a coil circuit configured to emit the high-power pulsed electromagnetic field signal,
a feedback sensor configured to receive a feedback signal from the coil circuit, and to transmit the feedback signal to the RF amplification stage connected to the applicator, wherein the feedback signal modifies an operation of the RF amplification stage to increase or decrease an intensity of the emitted high-power pulsed electromagnetic field signal,
wherein the two or more applicators are configured to apply the multiplexed signal to the two or more applicators so that each applicator emits a PEMF signal without interference.
