Abstract
A radio frequency (RF) device may include an RF signal source having a selectable frequency, an RF antenna, and an RF power amplifier module coupled between the RF signal source and the RF antenna. The RF power amplifier module may include at least one input tunable cavity impedance matching device, at least one output tunable cavity impedance matching device, and a power amplifier device connected therebetween. A controller may select the selectable frequency of the RF signal source, tune the at least one input tunable cavity impedance matching device based upon the selected frequency, and tune the at least one output tunable cavity impedance matching device based upon the selected frequency.
